"Pop rivets are rather week and may stick
too far into the glass channel."

I think I understand now.
You are concerned that the pop rivets will be a problem on theinside  of the windscreen side channel, right?
Could be so!
If you really want to use a conventional rivet, check out a reputable Fastener Supplier, they may have what you need.
