Yes, I have a scuba-tank carrier on two of my homemade refractors. Love 'em!
I either used Velcro to wrap the excess strap around the scope or simply cut it off and sealed the cut.
Very handy and useful as well as light.
Check the size of the tank that the carrier will hold to determine if it will fit your OTA, and see if you can determine the length of the handle. I have the loops around my OTAs outside the rings so they won't slide too close together.
If you aren't using rings on your scope, find a way to tighten the loops to keep them in place so they won't slide together too close to each other.
