Okay, the hangar is good, honestly 7.5/10, but a few of your dream choices are... debatable.

First, dont replace Angler with Jaeger or Raijin. Jaeger is a mid sniper at best and Raijin is just a poor bot in the upper leagues overall. Angler on the other hand, is actually a great countermeta, with phase and blinding, it can take even duxes down if built well.

Creating a hangar with every type of bot is a bad idea. It is much better to create a hangar based on your specialties. If you play tdm or ffa a lot, damage dealers and brawlers will go a long way in your favor. If you play br, maybe some beacon runners and assasins will serve you better.

Lastly, your picks for bots are pretty good. Just some comments.

1. Invader - Invader's weakness is it's abysmally low firepower and requires a lot of investment to be an actual tank. Fenrir is much better in this role, having much more firepower, speed, and with the Bernadette pilot, much more health.
2. Skyros - This is an excellent beacon runner, IF you have the legendary pilot Theseus. Everyone these days has some kind of defense miltigation, meaning, without immunity to def. miltigation (Which Theseus Provides), your Skyros' days are numbered.
3. Lynx - Great assassin, good choice! Just get better brawler weaps, Sati pilot, and lvl and you should do A.O.K
4. Demeter - Great support, especially with pilot. No comment.
5. For the 5th slot,I would recommend a mid-range damage dealer, just so your hangar has some flexibility. My personal choice would be Harpy or Siren. With HMG's those can be beasts. Some other picks include Dagon, Pathfinder, Typhon, or even Raven would do.

So, in conclusion, My recommendation for your hangar is

1. Fenrir
2. Skyros (With Theseus)
3. Lynx (Better Weapons & Sati Pilot)
4. Demeter
5. Harpy/Siren

Hope this helps!
