Thanks for the comment, Ken.
I only suggested a CW output to point out that adding FT8-type signal
processing techniques could be done in a manner that would be almost
transparent to the operator. Your are absolutely correct that "Mode-X"
does not have to be a CW-lookalike, and you are also correct that a CW
output could be added to almost any digital mode.
I hope that at least this thread will generate some consideration and
discussion of what might be possible, and maybe eventually people with
the right capabilities will step forward to turn it into reality. The
processing behind FT8 is simply too powerful to be left to FT8, given
that FT8 as implemented by WSJT-X is too rigid to be a universally
desirable contesting mode. I'm a founding member of an active
contesting club with roughly 150 members, and exactly two of them
bothered to participate in the most recent major FT8 contest. I wasn't
one of them.
I have given this a lot of thought over the last two years and have my
own ideas on what it MIGHT look like technically. I'd be happy to share
those with anyone who cares, but in my opinion the goal is simply to
achieve better signal-to-noise ratios (potentially on the order of 8 dB
better than CW) in a versatile enough manner that people will want to
use it for contesting.

AB7E is proposing a new digital mode of more general utility than FTx
but using similar error correcting techniques. That he's involving CW
(International Morse Code sent by keying a continuous wave oscillator)
in an artificial way clouds and confuses the issue. Exclude the
artificial CW part and it is an interesting concept to consider.
How would you design it? Why do we need it? What are its goals? What
activities should it support? Let's do that and come up with some
specifications.
If someone wants to design a digital mode post-processor to generate
Morse Code audio, that is a separate concept and it could be used with
any digital mode: Mode-X, RTTY, PSK, FTx, Olivia, Feld Hell, whatever.
I personally don't see a need for it and doubt it would be popular.
