can i convert the alchemist to airsoft?

The alchemost has a nioce prime and alot of power. my logic is that if it can propel a heavy dart decently far, then it should have no problem propeling a .20 bb (these numbers were kinda geusstimated im not rly knowlagable in airsoft). my plan is to replace the pusher and the barrel and make a mag adapter. it works in theory but i just wanted a second opinion.

btw, r/nerf wont let me post at all. how do i fix this?
