It should work just the same with acacia, but if acacia has significant amounts of other alkaloids, they will probably be there in the end product too.
I didn't measure how much ethanol I used, but if we take mimosa volume estimates and consider I added about 1-1.5x the volume of plant material in alcohol per pull, per 100g mimosa I probably used from 185ml to 277ml alcohol per pull. Then later obviously one will need smaller amounts to dissolve the freebase from the crude extraction.
