If Wonder Woman knew what Rogues powers were she would beat her, but if she didn't, the battle would go to Rogue. All it would take is a touch, and Rogue could basically hold onto Diana until she passed out, or maybe even dies.
This fight would be a complete stomp however if Diana was wearing protective gear.
If Rogue able to access all those powers(or even just most of them), she should take this pretty handily. Magneto alone would probably give Diana fits, and his is just one of the sets of abilities she has access to. Combine his abilities with those of Ms. Marvel, She Hulk, and Wolverine and Rogue should wipe the floor with Diana.
I think Stoic and Goob summed it up. Diana loses. Her only chance would be if she was fully armed with every bit of magical equipment and all the weapons she's ever used. Since that wasn't specified she doesn't get it or the win.
Even with the powerset she had during Claremont's Xrun, Rogue should take it. She was catching bullets and throwing them back before people could even react....
