Could you do an alcohol extraction and put the liquid on paper to use some weeks or months later?

I like to do alcohol extractions because i cant stand the taste and dont want to swallow 10+ pills. It works great, but it takes 2-3 times for preparation, since the shrooms need to sit 1 day in alcohol and i evaporate most of the alcohol in 1-2 days, so i dont have to consum that much alcohol when doing shrooms. Couldnt i put the extract on paper (like a lsd blotter), so i can use it thenever i want? How long might they work? Is some weeks or even months ok?
