hey, i once did it with chacrua and chaliponga. i did it in a diferent way as you are planing, more similar to a traditional rapé.
the way i found best was to reduce the brew to a very small amount (allready in goo state) and mix it with traditional indigenous ashes. then i let it dry, crushed it, and mixed it with a bit of tobacco.
Done this way, it was slightly active, not enough for full effect like yopo. it would remind me of the ayahuasca afterglow, and since i was in a long diet, i had some comunication with those plant spirits, but it was something very subtle.
it is an interesting experiment, but if your aim is just to have a DMT experience in a diferent ROA, i dont think its worth it.
anyway, i dont know if the traditional ashes are a stronger or weaker base then carbonates, and the tobacco might have prevented a bit the stronger DMT effect, so go for it, try with a small quantity first, and share your impressions, i will be interested to hear your results.
all best
