With great fear of this, I opened a question on SO a while ago and at the bottom linked to several other SO questions under the heading "similar but different, because ...", and it went quite well, although moderation was quite angry that I didn't choose an accepted answer within a day.

I don't know about Stack Overflow, which is the largest SE site, and may have some cultural differences.
But I'm pretty sure that accepting an answer within a day is strongly discouraged on all Stack Exchange sites in general. You should wait, at least one day before accepting it - some users may still want to answer it. I only accept answers when nobody posts new answers. Also, a user doesn't have to accept an answer, if none of the answer is helpful for solving the question - it has been discussed on Meta before.
Personally, if I asked a question and none of the answer solves the question, I'll accept the most helpful one. If none is helpful, I don't accept any answer, and usually I will be able to answer my own question and accept myself in the future.
I've tried that before too, but over-zealous mods still closed as a duplicate - I really believe a lot of them do that without even reading the question, or the question they say is a dupe :/
