GOTEK setup for reverse sleeper (lemmy.sdf.org)

My latest project is an XT-class build in a modern looking case (Sergey's Xi 8088) complete with LED fans, window in the side panel, etc.

Normally, I would try to source real floppy drives for a project like this. However, in this case, to make it more modern-looking, I'm going GOTEK+FlashFloppy.

My question is: let's say I want to be able to use most kinds of DOS floppy images, including 5.25", 3.5", double density and high density. If I configure the GOTEK in the BIOS as a 1.44mb drive, would it also accept 720k images? Would it also take 360k or 1.2mb images or would I need a second GOTEK configured as a virtual 5.25" drive to cover all the bases?

Thanks; when I've had the chance to clear some workspace I may set up a test bench and try a variety of floppy images from Winworld to see what works. I vaguely remember once having to use Winimage to copy files from a 360k image into a newly created 1.44mb image for one machine. Unfortunately, that approach (aside from being a bit inconvenient) wouldn't work for floppy booter games but perhaps it could be done with a raw copy tool and the correct arguments.
