I am assuming that by original versions you mean Pre 52 Batman and standard 616 versions of Captain America, Deadpool, and Wolverine? If so, I am going with Batman and Wolverine for the majority in this fight. Captain America vs Batman is always going to be more or less a 50-50 split any which way people cut it due to both guys bringing their own advantages to the table. Batman is superior raw technical skill, Steve is the better physicals specimen. Captain America has an almost perfect offense and defense in his shield while Batman has the more versatile set of gear. There really isn't any clear winner between those two.
Looking at the other sides of things, Wolverine should beat Deadpool. People always try to push that Wade is an equal to Logan through trying to show that he's stalemated him or given him trouble in past encounters when in viewed with context, Wade has usually given massive troubles to Wolverine when coming in prepped or going up against weakened versions of James. Wolverine is the only one between them rocking a legit win when he got serious and was beating Wade around in their Hydra base fight. Overall, Wolverine is bringing the superior raw technical skill, far better damage output with his adamantium claws, better durability with the adi skeleton, and better speed and strength which should let him beat Deadpool and turn the tide in his team's favor. Wade can and will put up a decent fight, but he isn't beating James.
I think Crossbones has a good chance to dish out some damage on DP, but not enough to take him down. They both have similar H2H skills, but Deadpool has the better physicals, and above everything else, his durability is off the charts.
There will be a lot of shooting going on, blood splattering all across the cold New York streets.....but at the end of the fight, DP will get up and Crossbones won't.
