Advice for carry-on suit garment bag for TALL traveler?

I'm tall and wear 48XL suits. I'm looking for any advice on finding a good travel garment bag that can fit in airline carry-on that allows me to pack tall or XL suit lengths. I've seen lots of positive reviews for the Halfday Carry-on Garment Roller, but it looks like it only fits regular-length suits. Any one have any experience trying to use the Halfday Roller with XL-length suits? Any fellow tall travelers out there have advice for a good carry-on bag that fits XL suits?
