Ace Combat is many things, many awesome things, but it's not a replacement for Crimson Skies.
You could give Project Wingman and it's DLC a try, or maybe track down a copy of HAWX? Star Wars Squadrons? Tonally, all 4 games/series are wildly different, so you kind of have to narrow down what particularly you liked about crimson skies beside the gameplay loop: the story, the themes, the lore, the music, etc.

The new Ace Combat that just came out is pretty phenomenal. Not sure it would scratch the Crimson Skies itch, but it’s worth a play anyway.
