Great! The sooner (after the freeze) we can do this, the better IMHO.
git-dpm looked good at the time, however the more I think about it, the
more I think gbp is the superior solution - especially for a team
effort. It is very easy to break gbp pq unless you are careful to follow
correct procedures. Once a broken repository is pushed (e.g. manual
changes to debian/patches/*), it is not easy to fix without liberal use
of pushing a rebased repository. Or starting git-dpm from scratch. If
there was a conflict with debian patches (fortunately this hasn't
happened to me yet), I think it would be very challenging to resolve the
conflict with git-dpm (not that gbp pq is going to be great in this
situation either, however I think it would be easier to understand what
is going on, and hence find a good solution). 

The concept to convert from git-dpm to gbp pq is very very easy: 

1. Delete debian/.git-dpm 
2. Unapply all patches. 
3. Commit and push. 

(repeat for all branches on all repositories) 

Step 2 is easier said then done. I can do it easy enough on my own
packages. I think we need a documented process anyone can follow. Plus
dealing with errors as required (e.g. if unapplying patches causes
conflicts due to non-compliant git-dpm package) - if anything like this
happens - hopefully on not many packages, these packages might require
manual processing. 

The obvious way "quilt pop -a" doesn't work, because the quilt .pc
directory does not exist, and quilt thinks the patches are already
unapplied. I sent an email previously with some (untested) suggestions I
had.
