I think on a tire this size and the fact todays tires are much better than they were when plugging was first said to be unsafe, there is no issue with plugs. It does sometimes cause another issue tho....plugs often don't hold air as well. Thats why i didn't ride it till it wore out....i was sick of pumping air into it every ride.
If you've ever seen a cross section cut out of a bald tire, you'll see that the rubber is still quite thick. The point is that there's still plenty of rubber for the plug to grip, so assuming that you've done a good job on the repair, it should hold just fine. I've never had the pleasure of trying this on a bike, but I've ridden on plugged car tires without issue.
I like the idea of melting the plug down.
