This is concerning on a technical ride, and I wondered if adding tape and then mounting the spare would give a better immediate bond?
Not sure what kind of technical ride you are talking about, but your concern seems way out there.
If the spare flatted, you're no worse off than every clincher rider out there, & I don't think they are losing sleep.
I had that happen once- rode through a flooded spot & side-wall cut the spare. Call of shame, but that's it.
You have to try pretty hard to roll even an unglued tubular, IMO.
