(Editor hat off.)

If you know that the peer understands the extended fields, then you've created an extension that redefines a frame type by mutual agreement, which is already legal.  Just redefine the frame in your extension, possibly with optional fields.

If you don't negotiate, the risk is that there are conflicting interpretations of this after-the-fields data.  In order to avoid that, you should move your particular interpretation / the extra fields to a new frame type.

I don't see a path in which stuffing excess data into a frame without negotiation is a wise choice.
