..haven't tried that, but if a good release agent is used on the barrel, should be able to slip-fit and allow some expansion/contraction.
Don't believe there is any real accuracy benefit from the standpoint of grouping, so long as the barrel isn't hog-tied to the band there doesn't seem to be any accuracy penalty either. Does seem to be a stability help on a hunting rifle that's likly to take the occasional stray "barrel smack". It won't turn a 2" grouping rifle into a 1/2" grouping one, but it will better keep the POI in one place.
Do realize that there will be marks on the gas tube...GOOD epoxy won't come off without a good bit or work (and heat) and the set screw is going to make a bite mark. Be sure you're going to keep the rifle before doing any custom work...will find few buyers who share your tastes.
Free floated (no bands at all), if the barrel is pressed a little out of line (like 1/10th inch), it tends to move right back. If pushed farther out of line, it tends to not come back to it's starting point. Band can be somewhat loose on the barrel, but if tight to the gas tube, the barrel wouldn't get moved enough to ruin your zero. So I do think getting the bands solid to the gas tube is more important than a really tight fit to the barrel.
And if we really get hosnest about it...the mounting system at the breech end just plain suxs. One medium screw and a dinky one, set close together, way back at the end of a long barrel just isn't going to promote stability.
