i don`t know why no ones tryed the SCSI to PCMCIA iv used it and it works fine,it may not be as fast as CF on a IDE bus,but its more flexable.
i have dual slots so i can transfer data between two CF cards,but it also has a advantage of HOT SWAP.
do a search on EBAY for device which fits in floppy bay.
this is what my device can do.
it can be config as one SCSI id but shows LUN 0 and LUN1 (two CF cards)
or
it can be config to use two SCSI ID unit 0 and unit 1 (but can be config upto unit 7 using two SCSI ID).
it`s also bootable but iv never tested my unit with CF cards but it does support CF cards,iv only tested my unit with two microdrives.
