I love that one of Robb's fears is becoming Robert. Not only is he named after Robert, but both Robb and Robert are based on Edward IV.

Gotta love when the Lord Commander breaks his vows.
Not the part about where he's sleeping with Ygritte, that's generally an ignored part of their vows, but the fact that Jon is technically married to Ygritte.

Ummmmmmmmmmmmm...
No
They would definitely not do a Red Wedding. First, Robb did not break his word in this scenario, so there's little motive of spite. Second, Robb has way more support in this scenario, given that he has a ton of Lords of the Reach and Dorne. Also, the Karstarks haven't betrayed him, and Roose hasn't been given command of the Infantry and used that to bleed off Robb's men.
But third, the Red Wedding would be a profoundly stupid move in this scenario. The Red Wedding wasn't effective because it decimated the Stark armies. It was effective because it eliminated the last Stark who the North could rally behind. With Bran and Rickon safe, and Robb having a child also safe at Winterfell. Roose and Walder would instantly be declared traitors and would be completely screwed. Remember, this they don't just have to worry about armies either, Dany has dragons as well. And it wouldn't make sense for Robb have brought more than a few noble companions to be guests and a few hundred men at arms to serve as an escort, since no mention of Moat Cailin being taken by the Ironborn has been given.
Fourth, part of why they did the Red Wedding was because Robb seemed destined to lose. A big part of that was the fact that he lost Winterfell and Moat Cailin. Sure, Tywin won at the Blackwater, still, but the Tyrells should not be as big a force as they were originally. Not only did thousands of men go over to Robb, but then there's thousands more who were killed for trying to go over to Stannis, or during the Battle of the Blackwater.

Gee
If only there were a castle that is unassailable, where Robb could leave Dany and Jaime within the Riverlands. Oh wait, that would be Riverrun, which funnily enough, was where Robb was also born.

Wait, how did Edmure get there? He's a prisoner at this point. If not, Robb not only doesn't need to cross, but since they would probably be headed towards Tywin who is marching up the Kingsroad since this means Jaime is not laying siege to Riverrun. This also means that Walder is in no position to be making demands of Robb either. Edmure is his liege. While Robb, Catelyn and the Blackfish were all of Tully descent, none of them were Walder's liege which was why he was able to make demands in the first place.
And Catelyn does not have the authority to arrange a betrothal between Edmure and one of Walder's daughters.

One thing to note:
Daenerys isn't the heir to anything.
The Targaryens were deposed. And given the fact that Robb has no reason not be loyal to Robert at this point, Robb would never call Daenerys the rightful Queen.

There is no reason to keep Dany such a big secret.
First, so far, I'm operating under the impression that book cannon is being used (with the non-Daenerys part of AGOT being pushed back). In the books, Robert was ignoring Dany and Viserys, until Dany married Khal Drogo. Prior to that, he hadn't ordered anyone after Dany. It's possible that Varys had sent assassins after them, since he has the whole Aegon thing, and he may have wanted to drive them to Illyrio so that they could use them for their plans, and some maybe thought they could kill Viserys and Daenerys to win the favor of the king, but there was never anything explicitly under Robert's orders until he learned Daenerys was with child.
Going based on that, Robert wouldn't care. Daenerys is now linked into the Baratheon regime through her marriage to Robb, who is Ned's heir, and Ned is Robert's closest friend. Her loyalty is assured.
Second, Robb and Ned could say that they just arranged a marriage between Robb and a Lyseni Noble woman. Girls who look like Dany are often from Lys.
