My thoughts were simply to prove Sheamus as a versitile wrestler and to fill the hole Batista left when turning heel for the dominant face character, although Show kinda has that covered for the moment but that certainly is just temporary. I am a fan of trying new wrestlers out as both face and heel no matter how successful their original run may be. It is a good way for wrestlers to prove themselves as good alrounders and for WWE to find out their strengths and weaknesses in the mid card, where it doesn't really matter if it fails before making a main event fail that would have huge reprocutions. I think a mid card run for Sheamus could be the best thing on that basis.
