Sure it is possible, but a bit complicated.  You would need to have a 
PIN diode switch (or relay) to short out the input to the non-keyed K2, 
as well as a few switches or relays to select which K2 is 
transmit-enabled Mic, PTT and antenna.  Some sequencing to make delay 
transmit until after the input is shorted would be desirable.
