Allegedly the Watcom linker can produce flat files directly:

http://wiki.osdev.org/Watcom

ELKS binaries are really simple; IIRC they're just a file header and
then the text and data segments concatenated together. (Anyone got a
link?) It may be possible to persuade the linker to emit them without
needing conversion.

I also see that the Watcom linker can emit ELF and COFF files, but I
don't know whether it can emit the 16-bit versions (which are a rather
esoteric discipline).

What format is the kernel image in?

The hard-to-find Watcom linker manual is here, and the FORMAT directive
is documentated on page 61:
