Alternate Universe Mane 6

Just something I drew for fun, they are not really OCs, since I based them all off the mane 6. I was just playing around with name synonyms and tried to come up with some characters that looked similar to the mane 6 but not completely the same. 

Sundown Twinkle, alternate Twilight Sparkle is from this picture I drew. fav.me/d8v1pi7
Applejack doesn't really have a synonym so I used a type of apple and a name similar to Jack.
She is Honeycrisp Jo. I was actually going to name her another fruit other than an apple because I thought all the apple names were taken by Applejack's family members. I went through names like Pineapple Jo, Mango Jo and Grapefruit Jo. I don't think there are any ponies named Honeycrisp so that's why I decided to use that.
Alternate Pinkie is Rosie Tart, I think that sounds kind of weird though.
Spectrum Rush is alternate Rainbow Dash. I really hate her design, I think she turned out to be an eyesore. 

Honestly I'm not to sure if I want to keep the names I chose for alternate Rarity and Fluttershy. They just sound kind of stupid, so if anyone has any other suggestions please tell me.

There are not many things to work as a synonym to Rarity so I thought of using Anomaly but I think it would be weird to name someone that.
I might call her Radiance.

I was think of calling alternate Fluttershy, Flittercoy, but there is already a pony named Flitter and Flittercoy sounds really dumb.
Or maybe I'll call her Tremblechary. 

It's supposed to be a different version of this www.google.com/search?newwindo… picture.

Edit: I changed Spectrum's colors a bit, does anyone think it looks better? I still don't like it.
