Some years ago I recall reading about possibly modifying TSS/8 to run on
more recent disks instead of the ancient DF32 (a whopping 32Kword fixed head
disk with up to three more slaved platters).
Did anyone actually implement the changes? I know it wouldn't work well on a
moving-head disk without significant changes, because the swapping is more
or less constant.

Or the RF08/RS08 -- luxurious compared to a DF32/DS32!

A zillion years ago, the DECUS library had a TSS/8 hack to make it run
on an RK05 (as the only disk I mean -- later TSS/8s already supported RKs
as data disks, unless I've gone senile). No idea how they managed that --
the wordiness of the DF/RF controllers penetrates deep into TSS/8's soul.
Maybe RFILE/WFILE weren't done compatibly with vanilla TSS/8? Dunno.
