OK.  This is even better.  This is very close to my dream radio which has
a "Clear To Send" input.  With this sort of capability, you can hold off
the RF as long as you like while any and everything external gets to the
right place.  Nice.  Do you still get a PTT output from the radio that
goes active when any transmit function is activated?  This I would call
"Request To Send"...

So, you cause the IF radio to transmit--  it asserts "Request to Send".
Your sequencer now starts and begins flipping relays and keying
transverters, amps, etc.  The last step the sequencer does is assert
"Clear to Send" back to the IF rig which allows it to finally make RF.

And this works no matter what mode the radio is in right?  CW, VOX, FM,
whatever.

Seems ideal to me...
