So, out of order:
If you're asking if an SE can read Apple IIgs floppies the answer is "maybe". PC Exchange 2.0 and later as well as "Apple File Exchange" (going back to System 6) can read 3.5" ProDOS disks. Also, and someone feel free to correct me if I'm wrong, I *think* you might be able to use DiskCopy to image one. But that's not KEGS.
Note that the imaging process may well not work on nonstandard disks like self-booting programs or anything copy protected.
Apple II disks are NOT compatible with the PC floppy controller. Or, as I said when I assumed you were talking about KEGS running on a PC, "Hardware No Workie".
That's a pretty rude thing to say, particularly when you haven't been overly clear about saying what exactly it is you're trying to do and what resources you really have at hand, leaving us to guess. Here's a suggestion: Try saying end-to-end what task it is you what to accomplish, IE, "I have a 3.5" disk from an Apple IIgs I want to copy somehow and run on an Apple IIe that only has a 5 1/4" drive; I have a PC with a 5 1/4" drive and a Macintosh SE, is there any way to make this happen?", instead of asking overly precise questions that don't really add up to the big picture.
And you said nothing about trying to use it with a Macintosh SE, you asked about KEGS, which unless there's some *other* KEGS emulator out there from the dark ages you're referring to only runs on 32bi+t Windows and UNIX systems. Getting frustrated because we didn't connect the dots and, uhm... wait, what are you talking about again? Apparently you know that KEGS doesn't work on your SE, so why are you asking if KEGS can read actual drives? There is no platform on which KEGS would run (other than *possibly* a very late model Beige Power Mac running Linux, and there I'm pretty sure there are driver issues) which comes standard with hardware capable of reading Apple GCR disks. So, no, the answer is that KEGS doesn't support physical floppies.

"Read and write almost any soft-sectored floppy disk format compatible with the PC floppy controller, including some traditionally copy-protected formats."
