Think outside range of both you’d better have a full blown “belt and suspenders “ set up. Separate props and running gear. Separate fuel supply. Primary (or both) prop protected by keel. Spurs or other line cutter.
The Lugger on my Nordhavn46 was really basic, natural aspirated, dry stack/keel cooler, nothing on the engine or controls were electronic. Ran WOT for days, only shut down to check the oil.
Soooo, all you really need is one reliable engine.
Until!
Was still running perfectly when the boat yard's ape pull a stand out before putting in another stand allowing the boat to fall over, generating a rather large hole in the port side.
Bummer... Hope ins panned out!
Sticking with my Cummins single as well. I have an emergency tiller that mounts through a panel on the swim platform.

WOT for days ??? , sounds like the designer screwed up !
Sure an industrial rated engine run at its 24/7 rating can take the use but its rare that WOT is cruise speed.
You also can with two long lines even if you don’t have a drogue. Tie in a bunch of knots and voila!! Warps. Vary the length of each and off you go without the weight, expense and complexity of two big engines. Will note the first few Artnautica 58 made in NZ were single screw. But the more recent ones made in the Netherlands are twins. However the twins are of very low HP. Little Yanmars , Betas and the like that you would see in a sailboat
