Personally I would probably just consider a system where players with Morality begin a session with 5 conflict. Then have a system for players to remove conflict (playing up positive moralities). However doing so would pretty much require that the GM prepare opportunities for players to remove that conflict during the course of any session, which ultimately, can get a bit gamey.
Honestly, I don't see much reason to put too much weight in light side paragon status. If players aren't generating much conflict, then generally they're probably being a bit light-sidey, and so they get a free destiny point at start of session and +2 strain, oh boy.
That destiny point and +2 strain is the fuel they need to justify spending a destiny point to suffer strain and conflict to use dark side pips on a force roll.
