Its surely possible.

Is this a prop hanging Pitts or Ultimate, or a WWI scale plane tho?

Have a look at www.maxamps.com for 100A capable packs and cells at 
realistic prices.

Have a look at www.neumotors.com for big ticket motors and so on.

Built lightly, 10lb is a realistic target weight, and that would need 
not much more than a kilowatt for pretty agressive performance, or maybe 
2kW for prop hanging. If you build it like a gasser tho, to take gasser 
vibration stresses, it could weigh in a lot heavier than that.
