Is it possible?

Wrong, you can remove the version check off the dedicated server exe and let people join from any version. BrandiniMP gave me one awhile back that let people join from any version. I think his dedicated server patcher can do it. The only problem is it only shows up on one version, but you can direct ip from any.

I think there's servers that you can join from any version, but I don't believe there is a server that appears on both server lists.

You would probably need to spoof the data that is sent to Gamespy. There is one version number that is sent to Gamespy which says which version the server is for. If you can send the same info, but change the version number for each version you want, you would be able to see it on those versions of the game.
