So this is for ESP8266? On ESP8266 512k builds you only have 12KB flash memory anyway, so it wouldn't gain you a lot! You can always just write a bunch of data somewhere else in flash and then just save some bootloader code like
eval(E.memoryArea( addr, len ))): http://www.espruino.com/Reference#l_E_memoryAreaAt the moment there isn't anything, but you could potentially write to the saved memory area yourself. It's only a two uint32s with 2 lengths in, then the data, then a 'magic byte' at the end:

Potentially
E.setBootCodecould be modified and the IDE could split data up and write it separately though.
