I have that Turks mod, but I don't want to modify Vincent into Cloud,  Cloud into Rufus etc. etc.    I'm simply making a dreamteam.
Cloud           -  Better Cloud from End Battle.
Cid              -   Reno
Young  Cloud -  Zack  (Yes, I know it's not perfect and he won't get used during any of the story sequences but I can use him out of battle and in the dream sequence just fine.)
Problem with Highwind I managed to fix via using lgp tools to do most of the dirtywork.  Highwind wasn't letting me save my edits, So I  imported my .bmp files, and then exported them as .tex files,  then used those tex files in lgptools.
My new problem is that I can't enter Junon, my game just crashes.
