Hi Julian,
It is quite possible that I misunderstand what you write but I don't see a problem with having a copy of targetUri in the payload.
An RP may (depending on proxying etc) compare this data with the HTTP header counterpart and fail if there is a mismatch.

An additional advantage with this arrangement is that signed messages become serializable and thus can easily be stored in databases, embedded in other objects, etc.
