Honestly I think the reasons Rogue and Wanda hate each other are easily enough dismissed if you think about it.
Rogue didn't hate Wanda after House of M... if anything she was the most sympathetic of the X-Men towards her. She only got angry at Wanda after Xaviers death... and Wanda really wasn't responsible for that. You can certainly say Wanda was responsible for the House of M stuff but again, Rogue wasn't really all that angry at Wanda over that prior to Xaviers death so it's easy enough to believe she's not really angry at Wanda over that now.
Physical relationship is a different matter... especially if Rogue can't control her powers.

There was such hate when Rogue of her own volition decided to explore if her feelings for Magneto were real. If Remender has Simon take over Rogue's body to do something she would oppose, this place would explode. Also, it would be awful. Taking agency away from yet another female character is not advised.
