I know there is a region revive and let the people drink patch to make them compatible and I know there is a patch to get region revive and imperial isle to work. Is there a way to make them all work together? Boss also says not to use the region revive and let the people drink patch with UL imperial isle.

Nope

Hmm...in my previous game I used all three and I could swear there was a patch for either all three or possibly for the three + AFK_Weye.
I worked the changes into my own custom patch though, so I don't know the actual name of the patch.
I've decided against LtPD in my upcoming game, though.
