I can only tell you that I had that setup working fine in an A4000 Desktop.
i.e.
Phase 5 scandoubler in video slot linked with its short cable to a CV64/3D which slotted in further back in the bottom slot of the daughterboard.
I also had a CV64 in the Zorro slot above, and could feed the phase 5 scandoublers output straight into the CV64's input if I wanted to use that card instead. Both cards could remain fitted in the A4000 (no need to take one out to use the other)
