No, it is not ok, surely not in a question. Remember that StackExchange is not a forum, questions have to be questions, and even beyond, have to be objective, one question per question etc. Package patch proposal doesn't sound like a question.
It is, however, ok to propose a patch to an existing package, but only in an answer. I believe that the maintainer of the package should be notified, so that they either accept or reject the patch.
If you have a patch proposal, just contact the package maintainer. TeX.SE is not a place for doing this, nor for open-ended discussions about such proposals.
