Some of 5e looks very much like various 3e psi.
Leveling Up instead of CL, is Augmentation then squeezed into Slots.
6th level spells and up are Wilder progression.
Warlock is encounter recharge.
There's a continuum that goes: raw Ardent --> 5e Multiclassing --> 3e Gestalt.
Hopefully, they only use 4e Psi in bits and pieces.
Powerpoints in other editions, works very differently
than infilling the A and E part of AEDU.
Certainly they could port this in, with no problems.
