You mean the OpenRCT2 project as a whole? That would be _very_ wrong. The intention was to extend RCT2 capabilities, in the way of more features and compatibility with modern (desktop) operating systems.
Talk about a different UI has only been mentioned as something that an outside contributor could pick up. The whole port was more or less a proof of concept, with the potential to work it out into something playable. The Android builds started failing at some point - we haven't intentionally retired them.
In general, we have too little time for the game as it is. There is still a lot we want to work on that concerns the game itself - that would need to be finished before shifting the focus to projects like this one.
All that's available of OpenRCT for Android is one or two really old obsolete builds. Forgive me if I'm wrong, but wasn't the whole point of this project to get RCT2 playable on Android? Since RCTClassic came along that doesn't seem to be a priority anymore. A game that runs is not necessarily a game that is playable. There was talk of a rewritten UI for mobile devices but that was literally years ago an I would have expected to have seen something of it by now so I don't hold much hope anymore, and especially since the retirement of the regular Android builds.
