You can compile the mono JIT to 1.2 MB on x86 by compiling with
CFLAGS=-Os. Add mscorlib and you're at slightly more than 3 MB.
You can remove most of the locale info in the runtime by
reading the info in
	mono/tools/locale-builder/Makefile.am
mscorlib has lots of culture-related data that you may want to remove
(you can save at least 200KB there). Atsushi may want to provide details
for this.
You can also configure mono to remove features that are not likely
needed on your system, like aot and the profiler. Run:
	./configure --enable-minimal=aot,profiler
There are other things that can be removed, too, like most of
metadata/verifier.c as well as lots of classes in mscorlib and other
assemblies. You can do it easily with the powerful tool known as
preprocessor conditional directive:
#if 0
/* unneeded features */
#endif

You'll be able to get an almost full-featured mono runtime in 2.5 MBs.
Good luck with your homework!
