Yeah, they're in some sort of gray area between canon and non-canon regarding the characters. But I think the way the weapons are used in the trailers are canon accurate.

And one of the wierd things with Myrtenaster and Weiss is that when red is activated on Myrtenaster, it blocks the giant armor yet it doesn't do anything fire related like in episode 6.
