This is known as diesel-electric, and is a stable mature technology.
It will certainly work, but cooling of the electric motors is one issue.
And size of the electric motors is another.
Industrial motors with VFDs will likely work fine, as they are widely
used with no problems.
This will allow you to use 3-phase power, at 220 V or 380 V that has
many benefits.
Connecting VFDs is easy, they are highly reliable, and very cheap, as
industrial stuff is keenly priced.
Proper electric cables, and conduits, will be a good idea.
Double insulated might be a good idea.
A heavy genset adds part of the weight back, but you gain by leaving out
the inefficient, heavy, noisy and expensive marine gearbox.
