Anything that adds dimensions is probably a bad idea for a UHC tournament. The goal is to get people together, not farther apart.
Any mod in that list that is late game stuff -- I'm assuming big reactors as a high-end power source will fit that -- will never be developed. Equally, stuff that is about making a base look prettier ... I don't see that being a thing either. Remember, UHC is fundamentally about the kill.
If you want to look into something to add for modded UHC, how about adding prayers? If you don't kill someone, they'll get away and recover. The "minor nicking to death" that normally features in Minecrack UHC goes away -- you can't count on the caving damage that people will have taken, and people will risk the nether for potions and extra healing in combat.
Blood Magic ... Seriously? How are you going to heal the damage you take just making a level one altar / any stones or tools?
Sync ... WTF?!?? So, if you kill someone, they disappear back to their base, and you actually have to find/hunt down their base to get rid of them for good ...
