"suicide" doors, or any other types will cost $$$...As far as shaving handles, most of them use an internal solenoid triggered by your key fob...In case of electrical failure, many of them have a mechanical "button" on the bottom of the rocker panel (hidden) that pops up and triggers the mechanism inside. Howwever, those don't always work great, either, so you could be screwed sometimes
I personally don't like shaved handles for that reason, although they look cool....As a close option, how about some flush-mounted door handles from another vehicle?
As an example only, these type was the same I had on my GTO (oem on 04-06), that they are grafting to another car:
May be too 'curvy' for the Jeep, so why I mention example only...next time you're out driving, check out some oem cars' handles...so many options!
