Hello,
It's possible, but you may want to describe what you're trying to accomplish to get a better response.
For example, are you trying to call a class-level (static) or instance method of your model? If it's a static function you can just call BModel:
ome_method() from an AModel function.
If you're working with instance methods you'll need to decide how the two instances know about each other. Will you pass a reference of the first instance to a method in the second?
Also, what's the relationship between the two models. Is one a descendant of the other, or does one own the other (composed of the other).
Could this all be better managed by a controller instead? Ideally a controller would act as the go-between for the two models.
