OK -- found an AHA-1542B in my stash (and a Seagate ST02 for good
measure) and I'm happy to report that ImageDisk does seem to cope with
128-byte sectors given a controller that works. (Though it is a bit
fussy, occasionally it'd stop reading properly and the only remedy
seemed to be to reboot the machine.) And I now have a bunch more images
up at:

Including several copies of CP/M (looks like 2.2), images of Multiplan,
Wordstar and a diagnostic disk. That should be the lot! Thanks for the
advice.

Here are all of the ISA controllers with a DP8473, extracted from an
old controller list
AHA-1542Bs show up at Weird Stuff fairly often. If you need one to
read the Altos floppies, LMK.
Thanks, Al! I'll have to check my box of ISA cards, I have a few
Adaptec AHA-15XX cards, maybe I actually have one that's on your
list. I think I may actually have the Trantor T128F installed in an
XT somewhere...
(And as a side note, I had a chance to make a detour and a short visit
to WeirdStuff on my cross-country road trip this summer. Wish I'd had
more than 20 minutes to browse around (and more room in the car!) ...)
