I'm assuming you mean a version that consumes 5 PE and multiplies stats like Interval/Channel, maybe Elem. Res./Phys. Res. and RPDT/RMDT by about x1.2 their current value and therefore also lower the chance for bad stats. (that'd already be a HUGE boost)
That's a -1 from me.
I say instead create an "enhanced" PE of sorts made from Epic Point + regular PE which does that; the server needs paying customers to stay alive (I am not one btw, but EP is already tradeable anyway).
Increasing rerolling speed would definitely be nice though.
