What would be the goals of the kickstarter campaign? I guess a new expansion, the iPad app, improved player(s) vs AI experience (more campaigns, a better AI etc.) and more UI improvements (maybe a whole new web app)? Then as strech goals (in case the target amount of money is exceeded greatly) there could be an Android app and even another new expansion (perhaps smaller than the first one).
From the other hand adapting this to iOS and Android require major UI and play controls redesign.
Actually since mouse hovering doesn't have a necessary function in battle, nor does right button clicking or the keyboard, it would be pretty easy to adapt battle UI to a touchscreen. Not that hard for the market or army management either: there is really just the "big card" which is a questionable design anyway.
