Collapsible stock in a TW5

[mr_nuts31]

I've heard that it is possible to install a collapsible stock into a Systema TW5 and I want to give it a try. I've been doing some research and I found out that most people did it by using a real steel stock and removing the fuse in order to put a stick type battery inside the charging handle.

Now I want to know is it possible to use an airsoft MP-5 collapsible stock for this (I'm looking at the VFC GBBR one as my option). Also, is it safe to run without a fuse (I'll be running 7.4v lipo stick for this).
