Have you thought about a non-Mercedes V8? I know the purists will choke themselves to hear it, but my dad and I put a Mustang 289 into a 108 years ago. Ford (or Chevy or MOPAR) parts are a heckuvalot cheaper to replace or fix, and you'll find more mechanics who "know" a domestic engine more than a Mercedes one. Additionally, there are a TON of aftermarket parts available to upgrade, trick out or make them better.
If you are dead set on a Mercedes V8, I'd advise to take your pick, oil pan be damned. After you place the thing in the engine bay for fitment (without the oil pan on), you can ascertain where the cross member is and whether it (or anything else) interferes with the pan.
ANY oil pan can be cut, modified or deepened and rewelded by any competent welder. If you use something domestic, go to Hot Rod magazine and find a ton of vendors who make custom pans (they also sell custom pickup tubes). You could use a Mercedes pan and have it customized through them, I would imagine...
Have you looked for a 6.9? (I'm not sure such a thing would fit in your bay though) One BEAST of an engine, and if memory serves, it doesn't have an oil sump - the thing has its own separate oil tank and electric oil pump (a system you can buy for cheap and use on any engine, BTW). An engine with a separate sump will sit lower in the engine bay as a result, giving you a better center of gravity...
