Well, if you use an "integration branch", rather than a whole separate
repository, that should simplify things, I think.

And, if the differences between the branches are limited to those 5
files, a checkout (if you even really need to check it out) will only
update those files that are different between the branches. It may even
be possible to do an "in index" merge, without even having a checkout,
if there are no conflicts.
