We're having arguments inside the team about what the rules say. I don't think its legal, but it'd be really nice if it was.

If you look at Figure 4-4, it shows an optional "backing"--though it's more of a clamping system for fabric--that is metal. However, I caution you that R24 (no subpart) and Figure 4-4 combine to bar any other type of metal backing (and note Al's comments on the heavy stuff inspectors have been telling teams to pull out of bumpers, as well--he is, after all, the lead lead robot inspector).

In my opinion, your opinion is correct.
