Custom, but not created, deck

I'm relatively new to the card collecting world. I'm sure I'm not the first person to come up with this idea (and maybe it's taboo in the card collecting world) but has anyone created a custom deck by pulling from different decks?

Example may be taking the jokers from one, the spades from another, the heart numbered from another and the heart face cards from yet another, etc.

If anyone else has done this or considered it, which decks would you take from to build yours?
