Nice. It's certainly do-able. NASA funded efforts in this direction from 1994 to 2001, with their Advanced General Aviation Transport Experiments
(AGATE) consortium. [1] Around 2011, they tried again.[2]
There were two main goals - better avionics capable of handling large numbers of small aircraft in busy airspace, and small jet engines for small aircraft. The Cirrus Vision Jet is partly an outgrowth of that effort. It is capable of finding an airport and landing automatically in an emergency. Plus it has a back-up parachute. It costs $2.3 million, though.
Cost, as usual, will be the problem. Many have set out to build modern low-cost general aviation aircraft. Some nice high-cost aircraft have resulted.
