I don't think you should hurry up that much. you might be able to get something or not. a 3 years deathline seems hard enough, I would hone your skills so that you can use them on anime (or something else if that route fails)

I have heard of foreign animators collaborating on anime sometimes for certain scenes. I don't know your current art level but you usually need some high kill for animation. that's something that might be plausible to do faster if you're good.

I'm going to give two links so that you can investigate a little:

Studio no border This studio was created by a French born animation who now works in Japan. The page is useful because you can see the profile of the foreigners working there and see what they do. I recomend reading interviews with the founder and learn how he got to japan, pretty interesting stuff.

https://blog.sakugabooru.com/ Sakuga blog talks a lot about the animation industry per se and sometimes they talk about foreigners on the industry. I recommend checking their articles to know how that world works.

If you have twitter try to follow freelancer animators that works sometimes with japan and you will learn stuff.

Nothing wrong with trying to achieve something, you might achieve it or not but I hope you can fun while trying at least.
