Awesome! That looks great. I was thinking of doing something similar to yours with EPS. I have a spare 1306 motor from where I upgraded my micro kadet to a 1407 and 5 300 MAH 2s batteries (man those things are cheap, if it wasn't for servos, tiny planes would be cheap). The little micros can handle wind better than you think. My 5oz micro sig can fly in gusts up to 10 mph (sustained winds lower of course). It can technically do more, but it is no fun. I like all your ideas though.
On a side note, that little guy was not happy with a 5x4 prop, so best to stick with a 5x3. (That is running 2S, I am sure 1s would have been fine).
