Depends. Under linux you can do a loopback mount. An other fix is to
down-format a 1.44 floppy disk.

File Manager (Winfile.exe) can format a standard 3.5" floppy to 720KB.

All you have to do is put some tape over the hole in corner of a 1.4
Meg floppy and the drive will treat it as if it was a 720 Kb floppy.

NOTE: the hole in the corner of a floppy case with a sliding cover is
the "Write Protect" hole; you need to cover the hole in the other
corner to emulate a 720 KB floppy. Some drives detect this with an LED
and almost any covering of the hole will work. Other drives use a
mechanical switch so you would need a fairly stiff cover, like several
layers of tape.

That is a veryu bad idea. 1.44M and 720M floppies use different
signal strengths. You will end up with a floppy that may be
unreadable very fast.

Nope, not when the OP wanted a quick and dirty workaround while waiting for the correct media.

Disagree - if it is a "virgin" disk it should be fine; the problems only
occurred when converting one formatted to 1 size to another (I think LD
to HD but IMWBW and even then I feel this applied only to 5.25" (genuine
floppy!) disks).

Your problem...

You're massively confusing what happens with 5¼" floppys with what happens with 3½" floppys.
