Should I bother with a sleeve on a thin wall PPA-CF PCC suppressor?

I plan on printing a slightly modified FTN.5 PCC. It will be dedicated to a 9mm AR to be tucked under the handguard. Because it will be tucked under the handguard, I will have to slim it up slightly to fit the 1.71" diameter handguard. I also run keymo muzzle devices so I modified the file to have HUB threads so I can put my keymo adapter on it so its easy to swap between my other 9mms in a pinch. If I slim it down to 1.71" and then open the threads up to 1.375x24 threads, it doesn't leave as much material as the original design around the thread side of the ftn.5 PCC. Would there be any strength benifit to shrinking the OD even more and epoxying on something like a 42mm x 40mm carbon fiber tube (leaving only 2.5mm thick wall of PPA-CF and 1mm of CF tube at the threads) or should it in theory be fine 100% printed at 1.71" OD with 1.375x24 threads? Another option I guess would be reinforcing with epoxy resin soaked carbon fiber sleeve stretched around it. I've only ever printed rimfire can until now so I don't have experience with sleeves or anything to know if its worth the trouble messing around with a 1mm thick carbon fiber tube or sleeping it with a resin soaked carbon fiber wrap but I'm trying to build a long term printed 9mm suppressor.
