They army of Rogues will be nuisances at the most. Hulk can keep swatting them away until she loses her MM powers. Then it's just a matter of time before he cleans them up.
Multiple Man multiplies each time he is hit. So if she absorbed his power... and didn't lose it... she'd be able to lay the hurt on baseline grey, savage or even regular professor hulk.
However as it is savage hulk... who gets stronger as the fight goes on... with an incredible healing factor... most likely the fight would start with hulk hitting rogue... rogue splitting into 3 or 4... who lay on the hulk... who turn into 12-16... hulks getting angrier meantime...
eventually hulks anger/strength/durability/healingfactor/speed... who increase beyond rogues ability to create more clones....
hulk wins... but the fight will last a couple hours at the very least.

She'll turn green and gain super-strength and durability to some degree. Apparently gamma radiation has no negative affects on her as she once absorbed She-Hulk's powers and was fine.
It depends. She loses her powers over time and It's not like she'll immediately be at his level when she touches him, especially when he swats them away. Probably to a few tons each Rogue, which isn't really enough.
Well according to past experiences with Ms Marvel and Sunfire as long as she drains them so they're almost dead she's fine...so assuming she drains and kills Jamie before the fight she should keep the powers permanently...
BTW even after she drains the lifeform she still keeps a part of them with her...hence that horrible recall Rogue....
However you do bring about a good point about her initial strength level when she touches him....I forgot about his thunderclap.
Rogue touches Hulk, he goes unconscious and she turns big and green. You have to have Skyfather power level at least, to break her hold on you and resist enough to knock her away.

The thing is, her powers don't work instantly on Hulk like they do on other people. She tried this maneuver on Grey Hulk by kissing him. It took Hulk a while to figure out what she was doing, but when he did he slapped her off. He felt weak from it, but it just made him angrier and, thus, stronger, so it didn't matter.
Savage is in another league in terms of strength and anger than Fixit. They touch him, he gets pissed and slaps them away. They duplicate and whatever strength he may have lost is restored. Repeat...
I know this would be a buzz kill because I didn't say anything but she can only have MM powers because I to believe it would be a little uneven if she had his strength to.
