Do you know how many people say the same thing and never do it? It's the biggest dream and the biggest budget as well. Sure, it's a similar block with a larger bore, but everything above and beyond that is entirely different and it's not realistic. I've seen maybe 1 S62 conversion that was done into a 740iL, and god only know how it truely drives on the road and in real world conditions because it was made into a show car, so the most road time that vehicle probably gets is on and off a trailer. You make it sound like the proper wiring is just something some guys can do in their garage over a weekend...it's not that simple. If someone it serious about doing this, save the $5-8k you'd blow on the engine alone, throw a custom turbo kit or a premade S/C kit from VF on there for around $6k and save yourself the wiring headache of an engine conversion.

Realistically, no shade tree mechanics will be swapping S62 into an M62 chassied car anytime soon because the dreamers realized how cost prohibitive it truely is. I looked into it as well since I had to replace my 7's engine within 4k of ownership. Swapping an LSx engine would be 10x easier (because it's been done plenty of times) and they have an obscene aftermarket following...do that, then we'll talk.
