I use to work at NAPA and did this on alternators for older tractors (99% of the time swapping pulleys the opposite way we're trying to go here) but it could be as simple as finding a serpentine pulley that will fit the stock isolated alternator and building a custom bracket to mount it.

That might work as its an equalizer and not a regular standard isolator. That vanner is a heck of a lot different than the battery isolator in your boat or in my plow truck. The vanner is costly though ($350 for a used one on a popular auction site) and if it ever fails you have no cheap way to...

A battery isolator is more designed around using one 12 volt alternator to charge 2 separate batteries so it wouldn't work for the CUCVs combined 12/24 volt system as there's no way to get 24 volts from it.
