I'm a little late to post here but I looked at the tweak list and to me it can be broken down into a few parts
-themed
-pulling stuff from ics? (Graphics drivers too probably)
-"tweaks" aka scripts that, mostly via placebo effect, appear to improve performance
-kernel.
If someone ports this rom, it'll likely be buggy and lose any performance gains. Plus we lose the kernel which I think is the biggest part.
If you guys really want this then I'd suggest hunting down the tweaks, finding a similar theme, and putting it in a stock iho rom. Then ask a dev to make a similar kernel. (I'm currently hunting down the kernel to see what's different.)
