Yes but that's the least of it in my opinion. It is difficult, if

If it were possible lots of other people would have done it by now.
High power to weight ratio is what outboards excel at - diesels, not
so much.

Nothing is impossible. You design the tool to do the job. This isn't going
to be every ones engine. E-Tech has that wrapped up. This is a diesel.
Things change!

Some things don't change. By necessity diesels operate at higher
compression ratios which requires heavier cylinders and heads.
There's no way to save weight there without compromising durability.
