Just read the blurb at IGN and Geek Speak with pics of the "I Am Captain America" variant covers which will be released in June and July to coincide with the Captain America movie.
Here are the links:

(Check the Geek Speak link as it mentions that the July variant covers will feature an "Uncanny X-Force No. 12 variant by
Chris Stevens"!).
Here's a description of the idea behind the covers:
"Marvel has given Captain America the Rosie the Riveter treatment with a new series of variant covers called “I Am Captain America,” a chest-swelling, Rockwellean spin on the Sentinel of Liberty. The covers hit June and July to celebrate Captain America: The First Avenger, which hits July 22.
The variant covers showcase real-world heroes like cops, doctors, blue collar workers and other diverse vocations and ethnicities, with references to a certain shield and other red, white and blue nods to Cap thrown in. The series includes art by Marvel chief creative officer Joe Quesada as well as Alex Maleev, Marko Djurdjevic and Ed McGuiness."
Meanwhile, one of my clients (Colin Wilson) contributed one of the 12 covers featured - it's the Moon Knight variant featuring a Western scene which is very familiar territory for Colin who has illustrated the French Western hero "Blueberry" books and the Italian Western creation, "Tex Willer".
This is Colin's first work for Marvel -

Best,
Royd (looking forward to seeing Chris Stevens' variant cover image released).
Colin isn't a fan of "spandex" but seems to have an affinity for some heroes (Batman being one of them so I'm guessing that MK is do-able).
Great to know that two guys I am a fan of may get a favorable answer!
