Mosfet usually fail short circuit while relay usually fail open circuit.

So damned if I do...

Relay have to be rated for DC voltage, AC rating is not enough!

Yes, I did a joystick driven kayak which uses 50 amp dc relays so I'm quite
familiar with those ratings.  I didn't consider nor have I done anything
like this with mosfets.
