Sure. That was close to the "standard" configuration at my office.
My early (16K base) 5150 had 2 360s, a 5.25 720, a 3.5 720, and an 8" (on
a separate controller)
One of the XTs had 2 360s and a 720.
One of my ATs had a 360, a 1.2, and 2 1.4s
Another had a 360, a 1.2, a 1.4, a 2.8 (on parallel port), and a floptical
(SCSI).
ALL of the machines in that office had more than 2 floppies.
I think that Monte ended up with most of that hardware; I don't know
whether he would be able to locate it, or how much survived when the
school dumpstered his collection.

DEVICE = DRIVER.SYS /D:physical-drive-number /F:drive-type (0=360,
1=1.2, 2=720, 7?=1.4)

If you are using an XT with 4 floppy support,
DRIVPARM can be used to override the configuration of a drive, but NOT
with the IBM BIOS!
