If Braxton switches to the H back role I don't believe he will log a lot of touches at least for the first 6-10 games. If you are going to contemplate switching Braxton to the H role it would have been critical to teach him the position and get him in that meeting room during spring practices. He doesn't have that edge yet, which he would need to block at the position and that would make logging lots of snaps difficult to begin with. Then if you begin mentioning all the other qualities Braxton would need to possess to be an elite option at the H position, you will likely realize just how far fetched the idea of him being a major contributer this season actually seems.
He would need to learn ball security first and foremost if he was going to play as a RB or WR. He would also need to possess the hands necessary to catch the ball in pads at full speed with defenders breathing down his neck, which is a lot harder than many fans realize. The list of qualities he would need to master before becoming A functional player at the position can go on seemingly forever.
I find it incredibly difficult to imagine him developing even half the skill set necessary to make the position switch, and those doubts are only magnified when you think about the fact that it has probably been 6-8 years since he even played a position other than QB during a game.
