You're losing it ski...
Most good PSU's have floating outputs, so until you link them together they are all independant.

I had that same DUHHHHH moment this morning at about 3am.
Vout,,,+Vout,,, -Vout, it's all relative...
33v difference between -28 and +5, make a +33v and tap out of that as required, of course the 'ground' at +28v will have to handle ALL of the 'return' current.
No problems now...

I guess I forgot to mention one key aspect of this 'project'.
I can't use a 'power supply' like we (we as in tinkerers, hobby type folks) think of power supplies.
What I really need is a 'brick' or at least an open frame PSU...but, as you can see from the comments above, I got this one licked....I hope...

Thanks for the pointers...
