Add some additional but small benefit to having swallowed many Powerscrolls: Like having eaten all 35 existing PS120 could give you 10 extra Mana.
1) It would give some fresh air to the powerscroll market, thus driving more people back to champ spawns, and more income not only for PvPers but also for crafters and fishers (because of the tailoring, blacksmithing and fishing powerscrolls)
2) It would create a new long term goal for developping chars to the max, yet it wouldn't create a huge imbalance (missing just a few PS would mean only 1 less extra mana)
3) It is simple to implement
I can't figure out any downside, but I'm sure some of the usual naysayers will
