Uh :/

May work. Note that Busybox needs uClibc, which needs just the kernel
*headers* to build. You'll still need uClibc before you can build busybox.

Would probably require some hacks, but at least they're mostly in one file.

No. No! Please, no! PLEASE DON'T EVER PUT BINARIES INTO SVN!
NEVER, EVER! DON'T EVEN THINK ABOUT IT!!!!
(I guess you knew I'd say that...)

You know the reasons. This would just cause maintenance headaches
further down the road.

See above. Good luck! :)
