This is mostly a problem if you have external transverters, amps,
pre-amps, etc. that don't take kindly to QSK operation.
My solution to this problem is to use the PTT (a foot-switch in my
case) to key the transverters, but not the rig. I'm using a stack of
Elecraft's external transverters connected to the low-level XV interface.
If I key the rig without first keying the transverters, nothing happens;
the low level drivers aren't phased by being unterminated. When I press
the foot switch, the selected transverter goes through its regular
sequencing, but doesn't key the K3, so CW-in-SSB still works.
I personally leave the K3 in vox mode, but the situation is the same
with, say, a hand-mike. Push the foot switch to sequence the
transverters, amps, pre-amps, etc., then PTT on the mike or just have at
it with the keys/paddles.
In terms of wiring, I simply disconnected the transverter stack's
key-in and key-out lines from the K3, and wired a foot switch to the
stack's key-in line.

But Elecraft's implementation of CW-in-SSB contains a bug that makes it almost
unusable for the intended purpose.
If signals are too weak for SSB, then it is almost always necessary to use
*slow* CW - probably much slower than the regular CW settings, resulting in
frequent and unwanted relay dropouts.
The normal, obvious 'fix' for these dropouts is to engage PTT for the duration
of the transmission, and this works fine in regular CW mode. But when using
CW-in-SSB it inexplicably does the exact opposite: engaging PTT *disallows* all
CW output!
This bug has been reported a number of times and is still waiting to be fixed.
