@Optimusprimebumblebee "Neo Astral-X" 123 - I wouldn't say no to that. Mind you, there's this Indiana Jones cameo in one of the Tomb Raider games.
(The following is copied from the link above):
"In Tomb Raider Anniversary you can find the boulder and if you dodge it at look closely at the boulder there's a smashed fedora and whip showing that The Boulder killed Indiana Jones this time."
Outside of that, seeing Tomb Raider cross over with the Uncharted series seems to be a popular choice.
As for myself, a crossover with the James Bond franchise "might" work if handled properly - although part of my idea for that is because Daniel Craig (who played the most recent incarnation of James Bond) starred in the 2001 Tomb Raider film.
To quote what I said on the James Bond wiki, "a crossover with Tomb Raider "might" work - maybe with the villain seeking some ancient artifacts to use as/to power a superweapon to demand ransom and/or blow something up (the classic 007 schtick), which would see Lara and James cross paths as Lara wants the artifacts while James needs to stop the villain.
I'd personally prefer Classic Lara in this case if it happened instead of the current incarnation - seeing Bond and Croft start off butting heads and verbally sparring because of their strong personalities before working together and coming to respect the other (without either been "deconstructed" to make the other look superficially better) sounds like something that could work."
Beyond that, maybe a crossover on Doctor Who using the "Land of Fiction" - especially since Doctor Who has referenced her. On top of that, the show has crossed over with Star Trek in the comics and one of the future "Christmas/Festive" specials was nearly a Harry Potter crossover, so having a crossover with Tomb Raider wouldn't be too off-putting.
The closest we've had to Lara in Doctor Who was in an episode called "Planet of the Dead", which had Lady Christina De Souza - a minor British Aristocrat and a burglar/thief who steals for the thrill of it - as a temporary companion of the Doctor: https://youtu.be/VyRnODcg4bI
