I'm thinking you could mount the head unit to a pack with some velcro straps and some brackets like this screwed into the side.
Biggest problem with the vex is the battery. You can go with a Lithium battery of the same size made for e-bikes. Battery + charger online for $125. Expensive but about half the weight. I'm running these in both my Aquaview and Vex and been happy with performance.
Another option mentioned recently by Slayer is using the Milwaukee 18 volt drill battery with the adapter that brings it down to 12 volts. It works!
