In terms of supporting third party implementations you would have to rely on that third party for said support.
Also, it looks like this relies on a 1.x version of SourceBans, it will not work with SourceBans 2 (at least not right now) but there's plenty of documentation for third parties to develop their own plugins and/or interfaces to sourcebans 2.
Well actually it is ENTIRELY possible... All i think you would have to do is maybe edit the sourcebans 2.0 and add a new game mode. Here i am assuming that sourcebans uses SourceQuery (or atleast i think so anyway) and SourceQuery supports querying Minecraft Servers since well... uses the Source RCON protocol. So yes it is entirely possible to do this, even without an external plugin.
I however am not sure how banning would work as you would need to create a separate plugin in Java that is similar to the sourcepawn plugin to add bans and such.
