There’s lots of theories on whether or not Loki is going to join the crew. The biggest (no pun intended) reasons he should join is to free the galleila giants stuck on punk hazard. That being said Loki himself doesn’t need to join the crew for that to happen technically only ragnir does. With Loki potentially reuniting with them when he’s fully healthy
Also in the mean time while ragnir is away Loki would definitely use his dad’s sword
