Trying to understad
As i understand in an A/B you first pull the dmt salt in to the acidified water and later make the DMT salt into DMT freebase by basefinig the allready acidified solution.

So i wonderd, If SWIM wanted to make some gelcaps containing DMT for oral use, could he:
Acidifie some water to around ph 3.
Add the bark
use some eggwhite to clean out some tannis.
filter the solution.
ad more acidified water to the bark
filter solution
repeat with acidified water and maybe ad one more eggwhite to get rid of some more tannis
repeat with acidified water and filtration until solution gets clear(ish).
reduce acidified water.
evaporate water and scrape up the dmt salt?

(or use acidified ethanol and freeze?) 60% ethanol will freeze around 37 C

Or will this yield very low?
