But 20k of RAM is enough to run eLua?

I did exactly this for the mizar32 last week, targetting 120K to be exact.
Use the "Mizar32-v0.9" branch, which has load of code-size hacks,
apply the AT32UC3A0128 configurations from
src/platform/avr32/MIZAR32/mizar32_conf.h and src/lua/luaconf.h to
your board and compile with
  scons target=lualong allocator=simple optram=0 rostrings=0

In our case this allowed us to fit in all the modules except net.*()

If you need FP or net for some reason, you'll need to disable other
Lua modules or features to make space.

Good luck!
