It worked like a charm!

Pictured with only three of us, but I'm sure 4 will work just fine. I didn't adjust it at all, so the positioning works fine, at least for my own purposes.
However, found a bug. Now that we did this, after we exit the shark blimp, the way our character models weapons, or anything really, it puts the hand way off.

I did science and had people log off and log back in, fixing the issue. Then getting back on the blimp and getting off and the problem returned. Very strange. Not breaking the game, just making the character models look funky.
