Don't trap yourself with a false notion that if everything is not 100%
optimum, the airplane will fall out of the sky. Keep it simple. The idea
is not to stretch the limits of the airplane's capabilities but to fly
within the known capabilities. If the airplane doesn't fit the mission
you desire, maybe a different design will be a better fit.

May be there is a better way to stretch out the CG envelope just a bit more
without modifying the fuselage or increase the HP of the powerplant,
perhaps?
Another rudimentary solution might be just to install one or two two-gallon
water tank to be placed where to make the CG just a bit tail heavy, and the
pilot could easily pull open the valve to dump the water quickly as needed.
A 2nd weight-balancing water bottle could be installed in the front to make
quick CG adjustment through dumping or pumping water back & forth.... This
could help stretching up the CG tolerance practically and cheaply, right?!
Stay and fly safely!
