No... not as THE central theme of the show.
Assuming Season 1 gives us about 16 hours of SHIELDtime in the here and now (2013 or there about), they just dedicate between 1 and 2 hours, scattered across (say) six episodes, to sing the ballad of a young Fury.
Many, many, MANY shows have used that particular structure. Of those, many have been successful.
