vc-dir has its own presentation logic, it's pretty complex.

'git diff' has a '-O' argument, which accepts <orderfile>. Maybe it'll 
help, but I kind of doubt that. Ideas welcome.

Here's a bigger feature I've wanted to see in VC for a while: commit 
from a diff.

There is a third-party package: https://github.com/caldwell/commit-patch

But it implements some of its logic in Perl, and the message buffer it 
creates is non-standard. I'd really like to see it ported to VC.

The idea is, you open a diff, maybe split some of the hunks, kill the 
ones you don't need (diff-mode supports all these operations), and then 
commit the remaining ones, from multiple files, if needed. Seems like a 
good replacement for 'git add -p' for Emacs power users.
