Yep - that is the whole purpose - get everyone drawing their own
stuff in KiCAD with copy/paste and prototype/review each other's work
asap. The sooner stuff is working the quicker everything else moves
forward. Leave some prototyping area or SODIMM edge connector or FPC
area to connect out to do debugging working on first PCB. It can be made
so as to be easy to be cut/snapped off.
