Ditto on just using the 135 hub in the 130-spaced frame. It will work just fine. little to no effort.
However, I have done exactly what you propose. That is, to run a 130 OLD hub in a 135 OLD hub shell. it’s not tough, just a bit fiddly to get the cones set, i.e., to get the hub/rim centered in the frame. You’ll need either a wheel dishing tool or at the very least a decent truing stand. Most (older) 135 hubs can fit, but you’ll be removing a few washers between the cones and the outer locknuts. Trying to get the hub/rim centered in the frame using the frame will be frustrating.
