[Elecraft] Why not a KX4?

My wish list for the KX3 would be to serve as K2 replacement,
price/performance wise. While I could list some UI and under-the-hood
improvements, and I agree with Tony's suggestion below, I want to make a
form-factor suggestion.

I'm imagining the KX3 repackaged so that it can be used alone as a QRP
rig, but can also be docked-into a larger chassis (K2-sized?) as its
front panel. That lager box could include integration of the guts of the
KXPA100, a bigger battery (like 6_Ah or so), a bigger speaker, a flip-up
or flip-out (on a side) display for an integral PX3 replacement. (Or
better from my perspective, a WiFi or Bluetooth interface sending
waterfall data to a phone or tablet app?)

Have it both ways: A high-end QRP rig, or a reasonably compact 100W
full-featured portable.

PS: Tony, my KX2 seems more frequency stable than my KX3 on WSPR.
