 that's fine as long as it's not the same connector / casework

 yes - which is why i'm not going to do that.  ever.  the lesson from
X25 and more recently Q-Seven and to some extent COM-Express (with
physical size variants) is very very clear: under ABSOLUTELY NO
CIRCUMSTANCES make anything "optional" [*1]

 not in the same casework / connector - absolutely not.

 the only thing is: we're running out of connectors/caseworks to
re-purpose.  ExpressCard is a possibility, for re-use with a
severely-cut-down set of interfaces.  only 26 pins is reallly tight
though.  but, if no SATA and no Ethernet and say LVDS, it'd be doable.


[*1] except unless it's done at the physical/firmware-negotiation
level such as multi-lane PCIe, USB1 thru 3, SATA1 thru 3, or 10 thru
Gigabit Ethernet.
