I doubt you could fit them all in to SR:LE and stay under the 255 plugin limit without some pretty brutal merging. Plus, the majority of the quest mods are already in the REGS pack, too. Which works well with SR:LE. :) Oh and Convenient Horses is actually already in SR:LE :) But I do agree that Wintermyst and Apocalypse are good. Cause I already use them in my setup.
