no this is a complete waste of time and mimosa. Might as well save it for drinking and not waste it. You will just end up with impure tannin rich resin with DMT salts in it.
What you can do is this..but it is more work than many other teks that use np solvents out there..so I dont get why you dont want to use limonene or vegetable oils etc..but if you still want to you can do this tek..and you can make changa and break through this way. This was the first tek I ever did and I just sort of made it up and it works. It smokes harsher than purer DMT though so beware of that.
Take the mimosa and boil it in a solution of water and vinegar..do 3 washes and then filter the liquid through a t-shirt and collect it all and reduce it..
Evaporate the tea down all the way into a dry resin..it will look like purple shiny stuff..scrape it up with a razor blade and mix in sodium carbonate and a tiny bit of water..just enough water to make a paste..mix it around a bit in a small litte dish or whatever as it freebases and then let it dry.
Once it is dry powder it up and do 3 washes on it with warm iso(if you cant do this safely than use room temp iso..do not risk blowing yourself up). Filter each wash through cotton balls if available..otherwise a t-shirt..and evaporate to a resin again.
Take this resin and dissolve in iso once more..it will be difficult to dissolve so this is why I say warm iso..or a hot water bath..mix it until everything that will dissolve is dissolved..then filter out the crap and collect the liquid.
let the liquid sit and if more crap drops out then either filter it better or get a dropper and remove the liquid from the sediment junk..
Now all you have to do is evaporate this onto some caapi leaf or whatever leaf you want to use for changa..What I did is this...if I used 100g of bark I added it to 2g of leaf..assuming 1.5% or more..so if you use 50g of bark use 1g of leaf. Stir it as it evaps so you have a consistant mix. Then you smoke it.
Dont just make rue tea and evap that onto it..it will just end up making a changa that is a sticky mess..this mimosa tek already makes a very stick changa, but it does do the job. I would manske the rue it is soooooo easy, and add some of that to the iso when you make the changa.
I never used ethanol but I dont see why you cant use it in place of iso.
NOTE..do not try this with other leafy sources or plants with more oils! The reason this tek works well enough is that mimosa does not have too many oils and fats. If you did this with chacruna for instance you would have an oily mess.
Long live the unwoke.
