What would happen if you caught a PokeBall with another PokeBall?


Consider the following scenario: A trainer is trying to catch a rare or strong
Pokemon, and figures that catching it in a PokeBall will have a low likelihood
of actually catching and containing it.

What would happen if, after the trainer threw the first PokeBall and before
the wild Pokemon breaks free, the trainer hit the occupied PokeBall with a
second PokeBall? Would the both the original PokeBall and the wild Pokemon be
"caught" by the second PokeBall? Would the wild Pokemon just be transferred
from the first PokeBall to the second PokeBall? Would this double the
likelihood that the Pokemon will be caught, due to the fact that it has to
break out of two balls instead of one?

If the PokeBalls can be "layered," and the probability that you catch a
Pokemon increases with how many PokeBalls you can layer on it, could you not
just keep layering PokeBalls until you reach the strength of a Great or Ultra
Ball?

We already know that inanimate objects and things other than Pokemon can be
"caught" by PokeBalls, as evidenced by [this
question](https://anime.stackexchange.com/q/2881/26439).




While it's not an ordinary Pokéball, the [Mewtwo
ball](http://pokemon.wikia.com/wiki/Mewtwo_Ball) is capable of capturing
another Pokéball inside it.

This is demonstrated in the [first Pokemon
movie](http://pokemon.wikia.com/wiki/MS001:_Pok%C3%A9mon_The_First_Movie_-
_Mewtwo_Strikes_Back) and quoted in the synopsis section of the movie's wiki
page. A gif of the event is below too:

Granted, this is a special kind of ball developed by Mewtwo, so I can't say
for sure in this answer whether a standard Pokéball would behave similarly.

Additionally, the catch rate for the Mewtwo ball is listed as 100% on the wiki
page. Therefore it's impossible to say whether it would increase the catch
chance of a wild pokémon through stacking, as it's a guaranteed capture with
just one.
