That sounds a little bit like a challenge or something, but I'll deflect that.

It's generally not a good idea to use devices of widely varying speed
on the same bus, especially if those devices are expected to talk
directly to each other. As for the exact technical reason? I'll have
to pull out the manuals and look it up... But I'm sure I'm about to
get the answer from you anyway, either supporting or not supporting

It will work, but performance might not be as good as it could be. And
scsi cards are cheap. Might as well buy another card.
