Looking for ideas...G4 bodies

[TexasGal]

So, I am not opposed to painting, first off, but I would rather try and save the body color on these first.  If there are no suitable solutions, then no worries!  I'll happily take suggestions on any generation, from 1-4, so feel free to shoot them all at me!

Ok, I have the following ponies that need to be used. 

Lyra - already made a Fizzy (though I didn't do twinkle eyes on her...I just did normal eyes)
Sunset Shimmer
Cherry Pie
Applejack - already have a few ideas, but could always use more!
Scootaloo - thought about a Baby Heartthrob, but haven't decided yet
Princess Celestia

And I have a Shining Armor I am stuck on two choices for....Doctor Whooves or Big Mac?  o.o

I vote Big Mac <3

[Epona]

Lyra - Mimic or Ice crystal (I know hes not a unicorn in G1 but he would look great as one)
Celestia - G2 Silver swirl or diamond glow
applejack - crumpet or tic-tac-toe
sunset shimmer - red roses
Cherry pie - Galaxy or Milky way
Shining armor - big mac
Scootaloo - baby flutterbye

[An-Gel Sakura]

Cherry pie - G1 Twilight, G4 Amethyst Star, G4 Royal Ribbon
Lyra - G4 Sea Spray, G4 Strawberry Lime
Pincess Cadance - G4 Fleur Dis Lee
AJ - G4 Apple Cobbler, G4 Ginger Gold
Shining Armor - G4 Prince Blueblood, G4 Fancy Pants
Scootaloo _ baby G4 Sunstone

If you can sand off horns, you can make plenty more.

Great suggestions so far guys!  And I am game to try and sand/cut/shave off horns, so feel free to offer more suggestions!  I just get stumped with matching body colors up correctly sometimes.  >.<
