I could build and upload an updated dpkg somewhere...

I see that modes/clang10 mangles some files directly, and while this
makes me cringe a bit, what about instead adding a
modes/dpkg-fixfilepath doing something like:

  sed -i -e 's,fixfilepath => 0,fixfilepath => 1,g' /usr/share/perl5/Dpkg/Vendor/Debian.pm

Is this an acceptible way forward? If not, I can prepare a repository
with a modifed dpkg and follow the modes/gcc10 example.

Yes.
