Thinking about moving for work - custody complications

Got offered a job in Austin, I'm currently in Denver. 50/50 custody with my two kids (8 and 11). Salary increase is huge - like 40% more - but it would mean uprooting the kids and her probably fighting me on custody.

My lawyer says I'd need her permission or a court order. She already told me "absolutely not." This isn't about being difficult, she's got her whole family here and neither of us moved away from this area lightly.

But like... I have to think about my career too? I can't just sacrifice everything. But I also don't want to be "that dad" who moved away for money.

Anyone navigated this? What were the real consequences?
