The patch below creates such a git-remote-bzr package:

Unfortunately, at least with breezy 3.0.1 it does not actually work. :-(
Here is what I got trying to clone a random repository:

Maybe it would be better to try and revive the original git-remote-bzr
package?  Paul Wise has attempted to port it to Python3[1], but I don't
know how far he got.
