Repaints: Where is the love? Ones that you would buy.

I'm only going to list ones that aren't already official. Can be from any line. Please keep it reasonable, something Hasbro can sell retail. I'll start by listing the obvious.
Alternators
Rumble -> Frenzy
Ravage -> Cheetor (it's another yellow car but battle ravage is BW so cheetor not an impossibility)
Mirage -> Dragstrip (why must all supped-up cars be yellow?)
Sideswipe -> Breakdown
Classics
Megatron -> Shockwave
Megatron -> Galvatron (I think they already said no to this)
Starscream -> Sunstorm (somebody'll say it)
(from another post/forum but i like, no gestalt though)
Optimus Prime -> Motormaster
Rodimus -> Breakdown
Mirage -> Dragstrip
Bumblebee -> Deadend (maybe another mold once 2.0 comes out)
Sideswipe -> Wildrider
Cybertron
Optimus Prime -> Ultra Magnus
Shortround -> Seaspray
Hardtop -> Beachcomber
Energon
Barricade -> Grimlock
Bonecrusher/Sledge -> Slag
Dustorm/Wideload -> Sludge
Sky Shadow/Treadshot -> Swoop
Blight/Kickback -> Snarl (only choice left)
(or swap slag and snarl)
Movie (it'll be hasbro so no licensing issues)
Dropkick -> Optimus Minor (okay, maybe not - hehe)
Longarm -> Hoist
Swindle -> Shockwave (a la Jin)
Swindle -> Camshaft 2.0 (remold the head at least)
Starscream -> Skywarp
Barricade -> Prowl/Red Alert (I don't know about this one, barricade's robot mode won't translate well)
(line's pretty new and a lot of repaint'll happen so I won't list them all)
Ironhide -> Ironhide (Red)
Ratchet -> Ironhide (Red)
Ironhide -> Ratchet (White)
Titanium
Thundercracker -> Skywarp (currently canceled)
Honorable mention
Optimus Prime -> Nemesis Prime/Scourge/Ultra Magnus
Any done seeker -> any undone seeker
Bumblebee -> Cliffjumper (this is like automatic for Hasbro, I don't know about the others for wide release since cliffjumper barely sells)
I'm sure there's more I'm missing
