So every time I get the urge to work on my KR2 I get the feeling I won't
much like flying it. It's just too short in length, seems to me it will be
touchy and never will be nice and stable, easy to fly, decent airplane for
cross country. That depresses me and removes my motivation.

John,
Get the project finished and decide if you enjoy flying it after you get
some time in it. I've heard this same concern for my 30+ years in the
KR community. It might be possible to enlarge the tail surfaces to
increase pitch stability if that is your major concern. Mark Langford
went from a modified KR2S to a standard KR2 and he has many hours of
cross country. My KR, with a 24" stretch, is no more pitch sensitive
than my truck is in directional control. I have very similar stick
forces and range of movement as I do steering wheel force and movement
driving my Toyota pickup. If you can drive to the airport you can
probably fly a KR.
If you have no time in aircraft with sensitive controls, simply insure
you are holding all controls neutral on takeoff, make a very gentle
rotation, and by 50 feet altitude you'll know what it take to control
the airplane. Initial "over control" will be the issue, not control
sensitivity. I've made the first flight on three totally different
types of aircraft and the first "successful" flight on a forth and it
worked the same for all four aircraft. The fourth, an STOL type, had 2
or 3 seconds of panic at liftoff because I had not confirmed elevator
neutral, it jumped in the air, and I made 2 cycles of PIO before
stabilizing it. The flight was successful after that.
Get back to the shop and start making dust again..................
