Yes, in fact it's what I've been doing the past few days. Luckily there's a long weekend coming up with lots of free time for me to work on it: XBattle style game rewritten in Unity. Plan is to get a basic version browserized so I can get some feedback from players. My list of features I want to add is already starting to grow exponentially (e.g. persistent multiplayer world: hop on to play the game whenever you have time, then leave your troops in a defensive position and hopefully nobody is able to break your defense while you're not playing ^^).
