If you swap in a 98on m62, you get 30lb.ft extra, plus has been proven time and again that m62s were pretty underrated as far as hp figures from the factory. many cars put down 260-270 at the wheels.
Would it be worth to swap one just for the hell of it? Hell no. But if yours died, yes it would be.
How hard is it? I think it's fairly straight forward. I don't exactly know what the wiring differences are and how hard it is to get that done, but as far as the engine itself, they are pretty much exactly the same, so it should bolt up without too much issue.
