Would't you be far better off to improve your amplifier(s) to QSK operation?
 Or alternatively, some Microham boxes will do that for you by plugging the
paddle into the Microham box instead of the rig.  That's what I do if I have
to use a non-QSK backup amp.  I enter those delay parameters into the
win-key section of the logging program, or if it does not handle that, into
the uHam router program.
