This might work, but beware, it may cause chain rubbing in a different spot instead: Where the chain passes close to the suspension pivot point. I had that problem before when I was using 11-speed derailer gearing, before the Alfine 11. CEBEP, I guess it's hard to know for sure without trying, but it's an easy thing to try.

CEBEP, I thought your chain rubbing problem was with the original, medium elastomer? Could the new harder elastomer allow 34-36t?

If not, it might be possible to raise the swingarm just enough by inserting a shim of a hard material between the elastomer and the swingarm. This must be done with great care and in small millimeter increments, and it may void the warranty. But done carefully it could allow you to use the 36t.
