Hidan can't be killed. C4 won't work on him, especially since we know Hidan can survive as a talking head.
If Gaara's ordinary sand could defend some of the blast from C4, I don't doubt Sasori's iron sand could do a better job. Nonetheless, C4 is just too unfair because it would kill everyone except Deidara (or it could via suicide). But without it Sasori and Kakuzu stomp terribly.
I don't think that Kakuzu and Sasori would allow to Deidara enough time to use his C4. Evne if he did, I don't think that Sasori would be affected by it (considering he is a puppet that doesn't breathe) and Kakuzu has 5 hearts to sustain him. Sandaime Kazekage puppet + all 5 elemental manipulations trumps Hidan and Deidara in this case.
