Yeah I don't think it's going to cause any catastrophic failures or quickly destroy the tyre or anything, I would just be interested in the condition of the tyre after a reasonable journey, say Auckland to Taupo and back (which I do a couple of times a year for the Epic rides). But, as you say, if wear does become an issue, a spare rim with a decent road tyre on it would be perfect as an in-transit solution.
The only other possible concern is if you're unclipping the chain on a regular basis, you should carry a spare join link with you when you go riding, as they don't seem to like being unclipped and reclipped too often.
