None of Deidara's C1 attacks could connect until Deidara attacked the village, and Gaara was able to crush his arm.
Considering he was able to convert the land to sand before, I don't see why he can't do the same here.
Of course, we don't know how he would fare against C2, but we know that his Sand is at least strong enough to withstand C3.
He could theoretically withstand C4 by shielding himself in that spherical sand structure.
That's all moot though, considering Deidara was able to outsmart Gaara >__>. Wonder if he'd be able to outsmart him again though.
