You should be able to do a fair bit with 256kB RAM. I have a nontrivial app layer implemented in roughly 3 kLOC of lua with a full Lua 5.3 + some bindings on an ESP32 and it consumes just over 100kB. This is not a data heavy app though, mostly business logic.

I am trying to do something similar.
Compiling Lua without parser, dump and undump, it increases the size
of my final binary by 41 KB.
With the libraries base, bit32, coroutine, math, string and table, I
have a total increase of 83 KB.
So you should be good with the 1 MB storage. I still have to check the
RAM consumption and the size of Lua bytecode.
