Although I didn't spend much time on this pic, I have spent a ton of time thinking about this. Please, please don't change the old horse and pony lines!! A) They are a part of cs history and I belive we should preserve it as we do the history of anything else! B) Really, what you are replacing them with, although beautiful, are not equimagine horses anymore! The resemble them but they aren't the same! C) You wouldn't be able to change all of them with out making them look weird (example: Roadkill pps) and also, in my opinion, some of the old designs, ESPECIALY pps, would look very strange on the new horses and ponies!
And finaly D) Can't you just do something where it's optional! We could turn on and off those lines (i'm not sure if that would actually work), beacause i really don't care that some of my items only fit on some horses! Ok now I'm done with my crazy spiel, thanks for reading, this stuff has just been driving me nuts and I really wanted to say it so here it is.
