Might wanna avoid roundwound Ernie Balls for this particular application...
NRector, if you want to just try out the technique, and aren't sure if you want to go all in yet, I'd put on something low-ish tension but skinny enough to fit in your bridge slots. Eurosonic/Presto lights or ultralights, Innovation Silver Slaps etc. Lots of string info available by searching - you might want to look in the Strings forum or the Rockabilly though.
Whether you need adjusters will depend on how high your string height is now, so that's something to take into consideration. A good place to start might be just swapping your G and D out for wackers, and see how that works out for you.
