Is it possible to switch archetypes?


Is it possible to start the Eldritch Knight progression then switch to another archetype, say Battle Master archetype, later?

I’m thinking that I’d like to get a Hammer of Thunderbolts, but if I do it would be really nice to have the Eldritch Knight archetypes’s weapon bond so that I can recall it easily instead of having to retrieve it every time I throw it far enough to stay out of the blast radius. (Throwing it at least 30′ would make it take more than a round for a typical dwarf to chase after it.) It looks like Eldritch Knight is the only way to get weapon bond, but I am not interested in any of the other Eldritch Knight abilities beyond that.
