Do you think this setup would be safe to carry Red Epic with Movi? I am thinking of going X8 or flat 6 with U7 motors. Regarding X8 loss, I think I would be in the same payload and flight time range with this two setups.
Personally, I wouldn't run Hexa for lifting Epic although it can lift it on the paper. I would opt for an X8 or flat octo for lifting heavy and expensive gear for the peace of mind in case of a motor failure in the air.
I think that you should go X8, but what Esc are you going to use with those motors that will currently work?
