RC11,

That's the kind of "reconfiguration" I was applying to my Sun Dancer. I really think it would change the entire way the plane handles and flies. After all the give and take the plane ends up substantially lighter and so it doesn't require as much engine as it did at its former weight. Add to that the fact that although this is LESS engine, it's got MORE power than a 30CC normally would, so it changes things from that end. The difference would appear to be small enough that it should be fine.
