I like Sonia as a character, but I dislike Legends in general. Sonia should've never been THERE, IMO. I think she's better fit for being the start of the Morris clan. It was already listed in the family tree that the Morris clan extends out of the Belmonts AFTER Trevor, but BEFORE Christopher. It would HAVE to be a DAUGHTER of the Belmonts who marries into the Morris clan, thus her children would inherit the Belmont blood, but would inherit the Morris surname. And that role, alone, would be VERY important when you bring Quincey, Johnny and Jonathan into the mix. And that has always been my thoughts on the matter. Sonia was TOO GOOD for Legends. Trevor was suposed to be the FIRST Belmont to kill Dracula, so Sonia doing so basically retcon's Trevor's importance. Trevor's main accomplishment, claim to fame, WAS the fact that he was the first to defeat Dracula. IGA comes off as being very biased regarding the games he loves. I think if I was that biased, I would've nixed Legends too. You don't mess with the storyline of the games he loves. You don't say something in CV3 was NOT correct. I think a lot of fans would actually be as biased. It's a fan's nature, actually. We all have our "loves" of games, and it's kinda like a lowblow when we see someone else make fun of our precious games.
AND, I still have that hunch that the Legends team made that game solely to capitalize on SotN's fame. There is no other reason Dracula and Alucard would be designed to look EXACTLY llike their SotN versions. I call it Alucard wanking. They just HAD to through Alucard into the picture, and make him Sonia's BOYFRIEND, no less. They could ONLY do that if the Belmont was female. That would be, IMO, sexist. Choosing to make a lead character female only so that she could be an object of affection to a cooler male character. Did they not think Sonia, alone, couldn't pull in the gamers? They had to bring in Alucard to get the SotN fanboys' attention. That, IMO, was wrong.
But yeah, it would be hard to see IGA "salvaging" her. If anything, it's much more easier to make another female heroine Belmont. I don't see IGA ever considering to salvage Nathan or Reinhardt. And that has nothing to do with gender. Resurrection was never completed, thus has never been a part of canon for the fact that it was never released. Victor falls into this category, and I definately don't see him being "recalled" to star in another game. Though I AM kinda glad Resurrection got scrapped. Didn't like how it looked and it was a travesty what they did to Sonia. She looked like a man.
