ORIGINAL: MTK
If I was to re-design the model I would reduce the span down to around 74", reduce the tip chord to about 8" and keep the root chord the same. I would increase the thickness to around 12% to offset the reduced drag of the smaller wing, and to allow for other mechanical advantages. Stab area reduction would also have to be done, down to around 250 sq inches give or take. The stab span would be reduced to around 35-40% of the wing span. But that's me, and I would be re-designing with a different purpose in mind: F3A pattern.

That's pretty much what I did to the the T2K, making it a Tempest
I kept the wing at 10% though and it seems to work fine. But almost every other number you just stated is almost identical. I also made the elevator slightly larger, but downsized the stab a good bit.
I can say for a fact it makes this plane snap ridiculously nice. I do have to carry a little more speed though, but it's not noticable to anyone but me. At least I don't think so.
It worked. We'll see how well this weekend I suppose. Jeez I need more practice...
