I think FML was made to be compatible with ALL existing Modloader mods, even JAR mods can just go in the mods folder. Correct me if I'm wrong, but that was my impression of FML.
While this is a pretty solid, I highly doubt the pack author got permission from IChun for the Portal Mod. Because, if I remember correctly, IChun said he'd never give anymore pack authors permission to include his mod in their pack. But that hasn't stopped anyone before. (DNS Tech pack...)
Only the Nano Sword can "easily" bust through Quantum Armor. And even that takes a while, but it is worth it, PvP-wise, because it will totally destroy the Quantum Armor, not just drain the charge. Closest thing I could think of that matched your request.
It won't work. I'm sorry, but Forge API and and all kinds of shaders conflict. They both edit the same base class files. Bug the shader developers for fixes.
