If the trails are relatively tame, I can't see why it would be a problem; I ride my 650b gravel bikes on damn near everything -- bike path, singletrack, fire roads, double-track, whatever; it's when things get ledgy, super fast, loose, and rutted that I definitely prefer my mountain bike. In any event, 650b (27.5) is my favorite wheel size for both gravel and mountain. Big tires and wide bars are your friend.
