I don't see how "Asking a Question" is not welcome - the [FAQ][1] explicitly mentions you can ask and [answer your own question][2]

> It’s also perfectly fine to ask and answer your own question, as long as you pretend you’re on Jeopardy! – phrase it in the form of a question.

So, do the same. Frame it as a question. Perhaps leave comment stating you will be answering it yourself. You might get a better answer/solution than what you have thought of
