You can find out with some simple tests once the alternator is assembled. Mail me directly for advice on this if you like. I tend to forget to look at this board after I enter a discussion.
My new 2008 plans (Wind turbine recipe book) contains a chapter with useful equations for this sort of stuff so that readers can in theory do the calcs alone, but I am still here to help. Sorry the new plans are only in metric units (millimeters) thus far, but I hope to convert them to inches before I visit North America next year.

If you use more turns and larger wire then the coils will not fit the stator. To fit the stator with more turns per coil, you will need to use thinner wire. The longer, thinner wire will have much higher resistance. So your maximum output will be reduced to about half. Using the 10 foot blade you can produce more power in low winds. But if you want high power in high winds, then the seven foot blade will actually deliver higher power without burning out, because it will have a lower internal resistance with its thicker wire.
Personally I tend to go for a larger diameter with a lower max power because that results in steadier power output, but most people prefer the idea of a high maximum power even if it is rarely actually seen due to the small diameter of the blades.
I hope you understand the trade-off.
