The combo 6/12 has been done successfully and sounds like your system just needs a bit of refinement. How much depends on how much you want to do. The relay to connect things all the time would be a good step.

IMHO, changing the evaporator to the trunk may not be totally satisfactory if you are used to having a nice flow of cool air hitting you directly. Not sure if you are just planning to move and adapt what you have or get a new one designed for the trunk. On some of the newer trunk units, capacity may be an issue since you have to cool the back seat area before you feel any benefit.

The belt slip may be an issue if the alternator needs to keep output high and is under load all the time AC is on. Some installations have been done by using a two groove pulley on the compressor with the second groove driving the alternator via a separate short belt.

If you would care to post any photos of your install, am sure there would be interest in seeing how yours was done and perhaps others will have suggestions.
