That's what I run on my Rivendell Clem, but homebrewed because I wanted silver non disc hubs. rhynolites aren't that heavy, 550g IIRC. The non disk Deore hubs are also considerably lighter. So it wouldn't be a fly, but could be reasonably light.
I'd have to look it up, but a late 80s super grizzly is probably going to be spaced for 130, or modern road hubs. That would be a better starting point. I don't see an off the shelf solution for this, other than finding some vintage wheels, or building up new ones.
