Well, have fun then. Let us know how it works out for you. I hope it does, but I'm not holding my breath either on function or mostly, durability as the gun is cheap, brittle plastic and not meant to have a supressor.
But just a word of advice - when you post a plan asking for advice and a bunch of experienced players tell you it's a bad idea, usually it is. If cost is a concern to you, you've picked the wrong hobby.
