No.
They put the reference in the Gameloft Game as a reference. The only reason they thought to do so was because fans liked the idea of it. Otherwise, he would be nameless pony 3, with his very obvious non-British accent.
The difference between Weird Al and David Tennant is that Weird Al was not included in an April Fools post, Weird Al took a small video with a fan who was a brony, and he offhandedly and jokingly said, "Who knows, maybe I might be on the show one of these days." The guys and gals working on the show ended up asking him due to popular demand from the fans, and he accepted because he's a fun lovin' silly guy.
Hooves and Roseluck/Rose is a mere coincidence. He's shown up next to may other ponies, some more than once.
The Hub posted the Doc Hooves pic because of the addition of the fan name (Note, Derpy was also named due to fans), and they wanted to celebrate Doctor Who. Plenty of other people did the same thing, releasing Doctor Who related pics.
Skyrim and Modern Warfare 3 were released on 11/11/11, which was also Rememberance day, but that does not mean any of those are related in any way. Neither does anything released on the same date.
BBC makes a reference to an MLP reference that was added due to fan references.
There are many background ponies that have a chance to get a screen name. Derpy Hooves got one. Why does it absolutely have to be Doc Hooves? Besides, he already has an official name, according to many, many products.
Spool of thread was one of the keys. Just like Rainbow Dash's medal. They both shined like the rainbow, and the rainbows are a recurring theme with the Elements of Harmony. Ever since the beginning.
Vinyl Scratch is also in the rainbow set. It's just a marketing thing. For all you know Vinyl Scratch could be getting a larger role in the show instead. There isn't even a guarantee anyone is getting a role in the show. Many other background ponies have been featured in plenty of other sets, but they don't get larger speaking roles.
