I don't see any problem with uploading it really, especially if it's a re-write as you say.
I'm not a site admin so this is just opinion on my understanding of the policy not policy itself.
The only possible issue might be with the addon name, but that should be trivial.
In other words I don't think you even need to ask, the moderators approving your upload will inform you if there's a problem with it.
On a sidenote I don't know what you mean by 'muddy the question' but the question is particularly useless and has imo a common-sense answer without specifics
