Can I submit full plans for just the shell of my extension, i.e.
foundations, slab, walls, windows, roof (I need these as 2 metres from
public sewer), then do all the rest on a building notice. This would
make the "full" plans simple enough for me to draw.

You *could* - but you might end up paying double the fee - because it would
be classed as two projects. Have a word with your Building Control dept and
get their take on it.
