Not a problem-
to be clear on my end. I do not work with either of them. So I can’t give you the specifics, but I have known people who have worked with both.
From my understanding you can work with Santa Muerte for just about anything. And probably Baphomet as well. The difference will come into their specialties and methods etc…
I would suggest Santa Muerte though. There is a lot of info out there about her. From my understanding Baphomet is more of a creation of someone from the…1800’s I believe it was? Maybe he is an egregore? I’m not sure…this whole part is muddled for me.
All in all, I’d say pick one, get to know them, then after that start a relationship with the other. Step by step
