You might check with the Heathkit H8 guys - It's been a while since I have
monitored that list, but I know that a couple of times in the past someone
on that list has organized a bulk order of 5.25" HS disks.
You could also program a little microcontroller to time the index
pulses and "fake" the sector pulses, thereby allowing the use of
much-more-common soft-sector disks - A few people have done this
over the years, and I think at one point someone was offering a
little board to do it.
Yes... We did this for the H8/H89 10-hole, hard-sector floppies on the
H-17/H-88-1 controller. I put an AVR microcontroller on a little board
that synthesizes the index holes and uses 3.5" floppies.
It's all written up here,

look for the "HSFE" Hard Sector Floppy Emulator
