0-100v 0-30a adjustable SMPS

[crackead]

Hi guys.
I recently got this schematic.

It is for a 0-50v 0-5a lab smps .
My question is what do i have to change, so it can be 0-100v 0-30a adjustable ?
I will Change-
ETD59 !!!
450khz fsw ?
Half or Full bridge ?
More slope compensation ?
430w 0.008r D-S on MOSFETs
SI8420 instead of gate drive transformer (GDT)

The big question- voltage or current mode ?
It will have a balance winding if half br.

And the biggest question- what values to change i the feedback (voltage set, current set, opamp network...)

Best wishes to all !
