Hero classes... Based on Professions?

[Dantastic]

One of the main reasons Blizzard gave for not making a new hero class: Death Knights felt like they should start at a higher level. You were already a hero.
So, wait. A tinker would have to have been a great engineer. And an Alchemist would have to already have to be a great alchemist. !!!
So what if, to unlock a Tinker, or some other class, you were required to reach level 55 with a character of a certain profession?
Think about it!

Engineer: Tinker
Scribe: Runemaster
Enchanter: ...Enchanter as a class? Int plate!
Blacksmith: A City of Heroes Mastermind-style pet class with suits of armor as pets please and thank you.
Tailor: Demon Hunter. Because of reasons. >.>
Alchemist: Alchemist
Leatherworking: Beast Master
Jewelcrafter: .....Okay, I give up.

But seriously! What classes would you like to see that could be implemented this way?
Think it's possible?

For those who haven't seen a City of Villains Mastermind:

It's pretty beast.

Just no. Tailor = demon hunter? Leather worker = beastmaster? The only two even remotely close are tinker and alchemist.

It was a joke, bro; I have no idea what they could possibly do with Tailor, or leatherworker. xD

The point was that Tinkers could be implemented as a Hero class, and not a regular class. It was implied that they wouldn't add any more.

I wouldn't want that to keep blizz from doing cool stuff to the professions.

Great. You mentioned tinker, now Teriz is probably gonna show up. It's not gonna happen. Already a profession. And most importantly, there's absolutely no lore behind them to have a reason to put them into the game. Unless wow becomes steam punk all of a sudden.
