Alright I think I have it down fairly solid for all 5 chars. I have my pip keys starting at F8 and ending at F12 and these are the macros I have for when I switch to a new leader

/script if GetPartyLeaderIndex() == 0 then if GetActionBarPage() == 1 then ChangeActionBarPage(2) else ChangeActionBarPage(1) end end /script PromoteToLeader("newleadername")

then for the returning macro

/changeactionbar 1

make sure on your 5 hotkeys that the new leaders macro /changeactionbar 2 since it's the one with all their normal abilities...

I'll start looking into movement binding to make the new leader take over the wsad and the old one to unbind them
