Just want to chime in that I had a dream to this effect last week, the exact same concept.
And I also have been waging (along with a few other people) various types of war on “God,” one major working we did as a group involved the Sun, and my part of it involved evoking the Black Sun into the regular Sun.
I’ll be lazy and paste what happened below rather than paraphrasing:
[quote=“Lady_Eva, post:6, topic:8508”]In the afternoon, the group worked to evoke into me, as medium, the combined energies of the sigil Claidheam created, as an aspect of the Spear Gungnir wielded only by Óðinn, and also various other spirits and forces, this time not as kind of “frog in a basket” guests, but as aspects of my own soul that were personifying these gods, as one with them in undifferentiated union of our sources.
This kind of work, of summoning the gods and then identifying with/as them, is covered in the PGM and I had previously practised being a vessel for the evoked form of Lilith, working with Succupedia from this forum (and which account I have yet to type up, mainly because the working hasn’t really ended!).
Outdoors, and in this intensified and amplified form, wearing a black blindfold for protection, I/We then evoked forth the Black Sun, using this image as its sigil (which this represents is something people will probably have to find out for themselves).
It was well past noon, the Sun was falling lower into the sky, and the time was pre-chosen by us as significant.
Instead of structuring the Black Sun in the sky, I invoked it into the physical Sun, as spirit into idol, in order to end any remaining association between the now-annihilated troll god and the physically present star.
What I Saw
The Black Sun manifested for me behind (on the far side of?) the physical Sun at first, as though some kind of force was repelling it – it felt slick, like two magnets placed with repelling poles that slide by each other.
I closed down the structure, dug deep, and then with a lot more force, evoked the heart of the Black Sun directly into the centre of our domestic Sun, this time keeping my focus fixed – arms outstretched, band protecting my eyes, and visualising this clearly through my spirit-enhanced clear vision.
I held the Black Sun inside our Sun and watched the entire sky turn to silver and then darken to black, and the combined SunDisk turn into liquid mercury
- and then in an instant, some kind of moment of crisis passed, and the Black Sun, and the soul of our Sun, collapsed into each other and created a shining white diamond in the centre.
Later, D & M both confirmed that they had seen the same shape, and although they were supporting me and not (obviously) staring directly at the Sun, they reported retinal after-images of this same diamond.
Finally, the diamond shattered (but far more like dandelion seeds than like breaking) and I invoked it down into humanity, commanding it to take root as it willed, in the hearts of the worthy, of those who desired it (or ever had, or ever would) and that it would reveal itself when the time is right.

I know you’re way beyond the stage of needing “proof” or confirmation of what you see, as am I, but the similarity between our experiences, and the fact I also worked with Ahriman some 3 years back (in my case, a relatively short-term stop-over on the way to some other personal work, not the in-depth work you’re performing) seem to have somewhat led us along similar lines, similar experiences, and similar beliefs, and I think this is interesting enough to mention! 
Something definitely shifted for me as a result of the overall working that was a part of (described here) - the ability to enter places that are totally physical in lucid dreams has continued, and I’ve been having prophetic dreams as well which seem to be linked to this.
I also understand time as a constraint on consciousness, that’s more of a personal project I’ve been working on, intermittantly, and have only touched on a few times, I found this interesting:
“If time is really like space, as suggested in §1, and if the way time and space are perceived depends on the physical constitution of the perceiving cognitive agent (if made of mainly mass, then time flows and space is; if made of mainly energy, then space flows and time is), then the picture of the universe that emerges is one of a “frozen” world, which some scientists have dubbed, appropriately, “block world” (e.g., Dickson[3] pp. 165 – 174). In such a world, every event that happened or could possibly happen is already there, laid out in the four-dimensional space-time continuum.” (My emphasis) Source
