:I would wait at least a week, and up to two. Threads older than 14 days are archived, so if the thread dies for that period of time, it can be considered resolved in that forum, provided there is a clear consensus. Since there are multiple proposals you might end up going to a straw poll or something to determine where support lies. Normally you want an uninvolved editor to determine consensus and close, but informally, if the outcome is clear, you could probably get away with that yourself. I hope that helps.
