Despite the scene in Cleaved, I would want to say no but at the same time it really comes down to how much Solaria loved Eclipsa in the end. Not to mention she was really disatified with what Mina has done and I want to believe she would be mad at the MHC for crstalizing her daughter and putting her granddaughter through all that pain at Saint Olgas.
I'd say she'd have a hard time adjusting to Eclipsa's relationship with Globgor, but in the end, she would've seen how much him and her daughter truly loved each other and the fact that Globgor wasn't all that bad of a monster, therefore maybe attempting to bring peace amongst the Mewmans and the monsters
Hate is a hard thing to understand. But YES, I believe that her dislike of the 'others', will be weakened enough to see another perspective. Namely that monsters may be more then homicidal obstacle in the path of royal expansion.
But we have to remember that her genocidal attitude towards monsters was more then personal. Her caring son in law or her sweet grand child could help with that part.
But the expansion of the her kingdom was strategic. They needed more land. They needed less raiders. Back in her day the best way to stop the raiders was to remove the naboers.
The great thing about the last episode is that this territorial problem was turned on it's head when the dimensions merged. Her kingdoms bloody mission to survival has come to an end.
I'm more concerned as to what would have happened if instead of dying solaria had been sent to the future and found out what the mhc and shastikan had done to her daughter. Because despite her hatred for monsters (and eclipsa being locked away because of it) she would not have taken kindly to how Eclipsa was treated, even if it was because she married a monster.
Oh hell yes. That would be interesting Anonymius. Solaria The Monster Carver was the Wrathful Queen of Mewni. Her laser-guided hatred towards the monsters was great. But her many mixed feelings towards her family was overwhelming. This general of the Solarian Army was able to focus feelings into her actions. That takes immense control. But she broke down in tears when she realized that her daughter was in love with a monster. And what was the famed monster carver response? She let a monster live.
We don't know a lot about what next. But her future son-in-law survived. And Eclipsa retained her right to the throne. This is why I do not think that she would ever allow anyone to harm members of her own family.
I believe that judgement day will be perpetrators doom. When do you want her to reappear?
