I made my closed question more clear per recommendations and would like some votes. How, if at all, can the edits be promoted or bumped for a new audience?
Edits bump posts the front page, however, if a post has a score of -4 or less it won't show on the homepage (to clarify it will still show on the tag page). On top of that a closed question will also go to the reopen queue on the first body edit after closure. Unfortunately for yourself this question is at a score of -5. The question was bumped to the reopen queue with your latest edit. After consideration I voted to leave it closed though. It's not 100% clear what you're asking, is pretty opinion based and is even somewhat off topic for asking about the real world.
That really only leaves you with a handful of options:
Ask in chat: You can ask why it is closed in chat, how to improve it, for people to review it etc. etc. There's usually someone around, even if lurking, that might be able to help you.
Ask on meta: Like in chat you can ask how to improve it or even ask to get it reopened and someone is sure to either explain why it shouldn't be reopened or what needs to be done.
You could ping commenters on the question and let them know you've addressed some of the issues they've raised. However, use some caution here, don't over ping someone or bug them and don't ping bunches at once i.e. don't "spam" people with pings.
At 250 reputation you will be able to vote to reopen your own posts which will send it to the reopen queue to get eyes on it.
Aside from those option I'm not sure there really is anything else you can do.
On a side note I'm aware your question is more asking how to get more eyes on a question to review it to see if it need reopening. However, your title "Is it possible to bump or promote an edit to get more eyes on it?" isn't really a thing. You can get more eyes on a post but not really on an edit (unless you link the revision of something like that).
