Vin Diesel Up For A Second Marvel Role?!?

Could Vin Diesel, who voices the character of Groot in Guardians of the Galaxy, a character who only speaks one "I Am Groot" phrase be up for a second role in the Marvel Cinematic Universe? In a recent post on his Facebook page, the actor posted the following:

"Vin and Marvel... you all made it happen! I get the strange feeling that Marvel thinks I'm Inhuman... Haha."

Now being that Groot is an alien character and the picture Diesel posted with the caption was that of Groot, he could simply have just been talking about the tree-based life-form he is currently portraying. However this is the Internet so we always like to speculate, right? Some are sugesting that Diesel could be hinting at another role. The use of the word "Inhuman" has some thinking that the actor could be working on a second role for Marvel as one of the characters from the human off-shoot race known as the Inhumans. Lead by a powerful, but never speaking leader known as Black-Bolt, who if speaks can lay waste to cities with the sound of his voice.

Back when word broke that Diesel was in talks with Marvel for one it's upcoming movies, word was it would be for a future movie down the road sometime around 2017, as opposed to a more immediate one as we ended up seeing with Groot. Being that Groot is a CGI based character who only speaks one phrase, it's not out of the realm of impossibility that the actor could take on a second role. Especially if that character never speaks at all, such as the Inhumans leader Black Bolt. This of course is all purely speculation at the hands of the Internet gossipers, but time will tell is any of it pans out.

What do you think, would Diesel make for a good Inhuman?
