Im not sure if this is available somewhere or if someone else suggested it but it would be great to get a double speciality breed for an account, id easily buy it in the cash shop! Maybe make it for a duration of your upgrade ? Or for a certain amount of time!

Ooh yes I like this idea! :)

I can't imagine they'd go for this because it would limit the money being spent on upgrades because players could easily train 2 breeds on one upgrade versus having to purchase upgrades on 2 accounts. So HP would lose money which it needs people spending real money to keep it running.

It's been suggested many times over the years. 

Answer is still no, basically for the reason Nad said.

Ah yeah i get it but a lot of people breed more than 2 breeds I think if they change enough for it thry can even it ok and/ or still make money
