I put on the largest dimension SBW faux gut strings and ir worked fine modifying both the bridge and nut slots with wood files, as I would on upright. Start with triangular file to set depth and then rounded that out with round rat file. Didn't love the low E for lack of tone and put on an Innovation Silver Slap for that one. The problem yoy may not anticipate is the tuners. You have to shave the end of E and A diameter strings to fit in tuner itself but once thats done, it works fine.
Pro-tip: the preamp is kind of horrible. Set to send a signal way too hot. Turn it way down like to 1/3 if full volume. Since you are interested in liw tension gut-like strings, I assume you are interested in slap. I find its built in pickup registers neck slap impact pretty well but only down by that sweet spot about 1/3 up or lower. Which is about how hot the signal coming from Shadow Rockabilly Pro preamp on my upright is. Like I said the preamp is set ridiculously hot. It distorts in the bass if at full volume, but tone for both pizz and slap is decent if you set the volume much lower, boost gain on your amp.
