Well, nightmares are dreams, arent they?
I'd give this a "no".
What you can is look for a Side-Expansion - to Zorro II - Adapter (aka Busboard). Those with two ZII-Slots are even home-made. You can also look for a Trumpcard 500 pro, which had one inside.
Then you can get an Algor or Highway (USB!!) and put a Norway (Ethernet!!) on it. works like a charm. If you replace the actual Trumpcard SCSI-Adaptor, you can even go for a Buddha instead and get new IDE drives (even CD-Roms and notebook 2.5"-HDDs), a Soundcard (Delfina) for the clockport, and / or use the expansion slot of the Buddha. See
http://www.ami.ga for more info.
You need the busboard elsewhere, though. Manuals for making one are on AMINet, and if you ask nicely here on the forum somoen might be able to make one for you (though not necessarily for free

).
Have fun,
