The problem with using BEE to make mods is that in general, as a puzzle editor, PTI is very badly optimised and with the BEE2 stuff, it's even worse.
Adding unedited chambers as part of the mod would make sense other than that, but as a person with 10 years of Portal 2 mapping experience, I do not recommend using BEE2. I'm pretty sure you can tell that it isn't made as an alternative for Hammer that can easily be patched up with Hammer. Optimisation is a large part of mapping and if you want the game to run on slightly lower end computers, again I don't recommend using BEE2.
