Ok so here is my mane 5 next gen. There is a reason there are only 5. In my AU Pinkie Pie is infertile and that's why she likes to babysit. Also Spike is a full grown dragon so don't start calling me a Paedophile for shipping them _.
Ok so you have:

Rainbow dash x Soarin:Spectrum
She is a wonderbolt like her mother and father however she adds a graceful touch and adds dance. She is known as the "Jewelled Rainbow".

Fluttershy x Big Mac:Honey Bee
She is a honey farmer. She owns a bee farm and her mother and father help her.

Twilight x Flash: (Princess) Oracle.
She is technically a princess however she doesn't like being seen as a princess. Her job is to bring peace through out Equestria.

Spike x Rarity:Satin
She helps out at the boutique and loves creating fabric.

Applejack x Caramel:Toffee Apple
She hasn't discovered her talent yet however she loves creating sweets so maybe that's her talent. Wink/Razz
