I'd also say you can probably rewrite portions of the app like templates if it comes to it and as long as the app is generally well-thought out and tested, you'll be fine. It's really hard to know now what problems you'll run into, so pick something that seems decent based on what you know of the immediate problems at hand.
Sounds good to me :)
