Enlarged Bostonian (Pup/Prairie Bird) for S400

I'm planning on scratch-building an enlarged Prairie Bird using the Peck-Polymer's 16" kit's plan as a guide. Here's what I had in mind:

Roughly 60" span with about 500 square inches
Speed 400 with 4:1 inline gearbox
11x8 prop
8 cell 500AR pack

The gearbox, S400, prop and battery pack will be taken out of my electric 2M Bird. Do you think this power system will fly a model this large? I am planning on building the model extremely light with minimal plywood (except motor mount and polyhedral braces).

I would really like the plane to remain in the size mentioned and will make changes to the power system if necessary. Any suggestions? What would you recommend for a brushless set-up if I decide to upgrade?

Thanks for any suggestions.
