I did something similar a couple of years ago, but didn't want the old versions of SONAR nor many of the plugins.
I first installed SONAR Platinum then Cakewalk by BandLab, and then cherry-picked the plugins I wanted from old installers and Cakewalk Command Centre.
I managed to get all the plugins I wanted without the stuff I never used.
I never had X2, nor used V-Vocal (it was always a crashfest when I tried it).
... so pretty much what Scook said.
