I'd love it!
However I highly doubt Nintendo would do such a thing as they are 'very careful' with the Mario licence...
I have thought about the idea before, even the gameplay.. I think a choice for the player betweek 1st and 3rd person would be great, 1st person has better accuracy, 3rd has a greater view of the surroundings etc..
Then items such as lightening where every player lights up and can be seen through walls etc to the person who had the item..
You could pick up fludd and the poltergust 3000 for a different shooting style..
Could be very awesome..
