Idea for V2 or a future version

Two words: Triple Changers. Now, I was flipping through the forums like ten minutes ago and I was like, "aww I should make a triple changer. Wait, we can't. Hmm....idea!" But hear me out, okay? Don't just drop the triple changers right in there so anyone can make them. Here are thoughts for limitations:
1.) Normal Transformer costs €500 to build, so make Triple-Changers like €5000 or even €50000 so as to make it harder for people to gain (although 5k isn't that hard).
2.) I am still arguing over this in my head but here goes: Put a level restriction. Nothing too high (like not level 10) but maybe like level 2 or 3.
3.) Make it possible to have pre-existing Transformers become Triple-Changers for double the amount of € to build one and for a hefty sum of experience as well. This, also, could have a level restriction placed upon it, this time at a higher level like say 6 or 7.
