New package from one source

Recently future request for itk apache mpm was declined [1] by maintainer of apache (Joe Orton (jorton(a)redhat.com)). Please see bug for details. As was mentioned in there discussion I want package it and push to Fedora (it is open source and maintained). So, main question - is it normal situation have second package (I intend call it like apache-itk) with one source, which used in other rpm (apache) in repository? Is really there any legal issues or etc.? I think is most correct way is to so-maintain it in main apache package, but this suggestion also was declined. So, what is correct way to package and push to Fedora additional apache MPM? [1] https://bugzilla.redhat.com/show_bug.cgi?id=479575
