Obviously. I would do most of the work myself.
I think it would make sense to avoid the autogenerated dep just for the directory ownership. It's a fairly tedious thing to change though: update %files lists for each package that ships .pc files, update build requires for packages that now need to list BuildRequires: pkg-config, update the rpm dep generator. And then after all of that is done, verify that things still build, now that the autogenerated dep is gone from everything in the build root. It's a lot of changes to make, but if you want to go through the pain of doing all of that then I don't mind :)
Also, what should the BR be?
BuildRequires: /usr/bin/pkg-config
BuildRequires: pkg-config
BuildRequires: pkgconfig
BuildRequires: pkgconf
BuildRequires: pkgconf-pkg-config
