You can certainly do this, or you can add an amplifier keying circuit 
(see <http://www.elecraft.com/Apps/Amp_keying_ckt.htm>) to your QRP K2 
and have the K2 key the amplifier directly.  The amp key circuit is 
based on the 8r line which keys the amp 10-15ms before RF appears, and 
can be adjusted for a desired hold time afterwards.  Then you can use 
either the internal keyer or the Logikey.
