126mm to 132mm spacing on rear axle

I've been working on a 1995 Fuji Team that I picked up over the summer. It has Suntour Cyclone six speed components

My plans were to go to a seven speed freewheel with a Shimano 105 RD and use a set of Shimano RSX 2 x 7 Brifters.

Upon tearing it down, I discovered that the rear wheel is spaced for 126mm (Suntour LePree hub with six speed freewheel) and the rear dropouts are just under 132mm. (131.6)
My guess is it was originally 130mm -- the original spec was 8 speed. When you install the rear wheel , the QR has to pull the frame in to make up the 6mm difference.

I need to add a 3mm spacer on each side of the rear hub and a longer axle to get this wheel spaced properly.

Is that going to be too much extra spacing for that wheel, putting extra stress on the axle?

I also have a Shimano seven speed rear freehub spaced at 135mm-- i could re-space that to fit and rebuild the wheel, but I don't want to rebuild the wheel unless I have too.

Would you re-space the wheel or rebuild it with the freehub and get rid of the six speed hub?

It might be too much axle, it might not. My Raleigh is spaced at 130mm and for now I have a 126mm freewheel hub with extra spacers to make up the difference. I’ve broken one axle so far, replaced with one cut to length from a spare MTB parts hub. I’m a heavier guy and ride that bike on rough terrain, I’m guessing it could have been fine if I was riding it on the road only. I didn’t notice the broken axle until I removed the rear wheel to troubleshoot finicky shifting while climbing... QR skewers can put out impressive clamping force, depending. Or just stick with the 126 hub and pull in the dropouts while you gather some 8-10 speed parts to throw on.
