A couple of thoughts -
If you choose to use a 135 hub without cold setting (and realigning the dropouts afterwards) the dropout faces will be slightly misaligned and engagement of the QRs and locknuts will suffer as a result. With horizontal dropouts, the wheel can slip forward under load. This happened to me on my ‘87 High Sierra, which was spaced 130 from the factory for a 6 speed hub, but came to me with a cheap 135 replacement wheel. I was standing and grinding uphill when it happened. The bike came to a dead stop, and the wheel went up into my fender and bent it a little. Fortunately I was able to dismount without incident, but it could have been messy. I am over 200 pounds which didn’t help any.
That said, it will be much easier to find a 135 26” wheel with the freehub you want, unless you’re going to lace the wheel yourself. Many 135 spaced wheels can be respaced to 130 by shortening or replacing the axle and losing some spacers. The rim will have to be re-dished if you go this route.
