I could see that happening, but I've never even thought about that issue.
Assuming you were using modern chain instead of older chain (usually with taller sideplates), not much you could do 'cept use the 10t.
Then again, with the 11t version of those "Canadian" pullies with the alloy "hub caps", you could have filed the holes out to one side, then offset the pulley as needed!
