Welcome aboard.
First off, to get to the crux of your question, are you talking about joint legal custody, or physical custody? Joint legal custody just means she can have access to their records & have input on major life decisions, though in practice, the primary custodian is still firmly in the driver's seat.
I don't think Illinois officially recognizes a "joint custody" situation where the kids' time is split evenly between households. Here, if she has every other weekend "< parenting time >", that's considered joint custody.

Good thing our state isn't too big on alimony. If she's been living on her own for 2 years already, that should also help settle any issue with this before it even comes up.

If she doesn't even exercise the < parenting time > she has now, I don't see how she has a chance at getting more. Especially if you can show they're still getting good grades & doing well with you. But the second part could be cause for concern. Illinois uses numerous factors to determine who is the better parent to have primary custody. One of those is deciding who will make sure the kids maintain a healthy relationship with the other parent. Do you have documented proof that you've encouraged them to visit their mom? Phone records showing they call her now & then? Ever emailed her asking why she never showed up? Etc?

So, reading between the lines here, she was ordered to pay temporary child support until the divorce is finalized, right? Has she been keeping up with those payments, or did she stop paying? Illinois bases child support on net earnings (25% for 2 kids, if I'm remembering correctly). Her living expenses have absolutely zero to do with it, so what's her angle there?

There is little the courts can do to force teenagers to see someone they don't want to. I suspect things wouldn't change significantly even if your STBX had more parenting time on paper. Can't go to mom's this weekend, 'cause I don't wanna miss the game...
If it came down to it, do you think they would tell a judge in open court that they don't want to live with their mom? (They're old enough to do so now.) If so, they can tell their mom the same thing to her face, which would hopefully squash her bid for custody. If not, then perhaps it wouldn't be all bad to have them see a counselor who could essentially testify on their behalf.
