A speculative proposal to split Hoenn Pokédex into two generations

Same as here.

Similar to Unova's dex, Hoenn's dex has started to annoy me with its endless monsters. While the actual Hoenn Dex is not particularly large, with the 8 cross-generational species it has it becomes large, even with the two babies (Azurill and Wynaut) removed. Azurill and Wynaut will not be listed here for obvious reasons.
