Good idea to have a separate keying circuit - I suppose this may be
inevitable. There are, however, two things to bear in mind:
1. A card adds significantly to the cost of the package - it would
probably jump from $50 to $200. If it's a commercial product (i.e.
the circuit can't be copied easily) the cost for a multi-multi effort
could consequently rise from $50 to $1,200 or more.
2. Given that many people use notebooks (especially DXpeditioners)
you'd have to provide a boxed circuit running via a serial or
parallel port (and needing an extra power supply), rather than an
internal card (otherwise you reduce your market even further).

So how hard would it be to incorporate a morse driver on a card? You
could send the text to the card in a burst and the card would control
the speed (after being given suitable setup and control commands from
the PC). This would divorce the morse from the PC clock and avoid all
the interrupt and timing problems.
Since there appears to be a market for voice cards out there, why not
incorporate the morse feature in the same card as an option? Is the CW
market not large enough?
