"What are the implications of a CTOL carrier without an angled deck?"
Not sure if you are being ironic or comical here. The CVF design has an extensive portside sponson (the left side as you face forwards towards the pointy bit that makes the waves go frothy). A bit of paint and viola! an angled deck appears by magic.
EMALs/EMCAT's will drop into existing tunnels in the flight deck. Not sure what happens to the traps, but I'm sure those cunning designers have thought of that already
