You are right, Saffire Pro 24 and 40 have the ability to replace ADAT by
SPDIF, but I'm afraid that nothing has been yet implemented in this way
in FFADO. This is the first time a user ask for it.

I note this for a further exploration: it will require a little bit of
reverse engineering to detect how Focusrite implemented this
possibility. I'm afraid it will probably require a lot of additional
code  in FFADO, and I would have some difficulties to test, so do not
await for anything before a while, sorry.
