I liked the idea, so I wrote the plugin. Here is the first version:
https://github.com/q2apro/q2apro-tagexperts || https://www.q2apro.com/plugins/tagexperts
This is a plugin for Question2Answer that shows the best users based on received upvotes and posted answers for the tag specified.
Get the source code for this plugin directly from github
Extract the files.
Change language strings if needed.
Upload the files to a subfolder called q2apro-tagexperts inside the qa-plugin folder of your Q2A installation.
Go to your forum to the URL /tagexperts and enter your tag. Enjoy.
This is beta code. It is probably okay for production environments, but may not work exactly as expected. You bear the risk. Refunds will not be given!
