I'm doing the same with some 600 130mm hubs in a 126mm frame. I fitted a shorter axle and removed an axle spacer......not fitted it yet, so not sure whether i will need to redish...

I've been pondering about the best way to get a modern hub inside my non-modern frame. I was going to build another set of wheels myself, based around modern ultegra hubs. I notice that beneath the flashy decals they are just normal cup and cone jobs, and that I can loose about 5mm in the left hand spacer that is normally fitted, shortening the axle to take it down from 130mm to 125mm. I also have access to workshop facilities, so I could even thin down the lock nuts a little bit if required. Not sure if that will do the wheel dish many favours, but we'll see. That's the thought at the moment! You are right, i need to be a bit circumspect about this here 753 frame material!
Shortening a 130mm hub is ok in principle, but it does move the drive side flange very close to the centre line, while moving the nds flange much further from the centre line
this means that the tension balance is skewed very heavily toward the drive side, and you'd probably have to use a *lot* of tension on the drive side to get decent tension on the NDS
