I'm not entirely sure what you're asking for here but I think the
challenge may be that by splitting the refactoring into two separate
commits, it's hard to see the before and after when looking at the
commit in isolation.  By splitting them, it's more "a bunch of new code"
followed by "using new code" than it is a refactoring of existing code.

How about I squash the last two patches together so that its more
apparent that it's just a refactoring of existing code with the before
and after in a single patch?
