Why the separate repo? Why not upload to extras-devel (it'll let you override it in devel even if you're not the maintainer, and honestly, you could contact maintainer and ask him to let you maintain it, I'm sure at this point they'd know you'd do a better job than them - or if they don't respond, I think council can do something about that, last I checked, by prodding the right people who handle the repo management).
