I'll put my two cents on this;

Perhaps if we were talking 15 or 20 degrees of forward sweep you guys would
be correct, but I would like to point out that there have been several
sailplanes with forward sweep, the "Genesis" is one and Jim Marske has
designed several too. they have less than 5 degrees of forward sweep and are
TAILLESS... (the "Genesis" has a very small tail for pitch control)

For a KR "type" of airplane with say 3 degrees of "Leading Edge" forward
sweep wouldn't be hard and it wouldn't be UNSTABLE as it is all about
balancing forces. It's not like it's an X-29 or a Cornelius Mallard. And
might I add that the Bugatti model 100 had a small amount of forward
sweep...check it out at OSH this year, it's in there museum.

I do AGREE with Mark L though, it's not a KR anymore...

On a more basic note, I will add two things about forward sweep.
1. Your wings must be much stronger to handle the forces caused by the
negative stability.
2. It generally requires a computer controlled flight system to handle the
bending moments.  
Not recommended.
