One thing's certain though, Ed's not far enough to transmute Cap. There's also a couple of seconds delay before the "earth hands" grab you, so Cap would have time to dodge them.
I don't think that Capt. America would be possible to react if Ed was to transmute the ground he was standing on,raise it to about whatever distance in the air he needs to keep Capt. America from reaching him.And,at the same time as Ed was raised,all the ground that wasn't raised would instantly turn into the quickest sinking quick sand there has ever been,quick enough to take Capt. America down in less then a millisecond.And,once Capt. America was under,Ed would transmute the ground into solid granite with Capt. America still trapped inside.
With that said,and like I said before,Edward Elric FTW!!!
