I haven't used them, but I don't see any reason why those shouldn't work if you don't mind editing them yourself in game! I personally just stick to immersive weapons/armors and the patches, that adds in plenty for it to feel different and varied for me. Requiem itself even adds in a lot of weapons, like katanas, longarms, and such for more varied combat.
In fact, I am going to look into these programs myself. Requiem sometimes has a glitch with flipping the armor values of heavy and light shields, this could be a quick dirty fix to that.
From my experiment sadly I got CTD a lot with Skytweaks installed. I suppose I need to stablize everything first with requiem. I found several of my armor mods causing issues. UGH! I loved some of those armors. Especially the bad ass lich king set. Thankfully I don't need any heavy armors right now. Going archer/ranger for my next character.
