Of course it is sound! I invented it myself.
I presume you have an improvement on 2.d4 cxd4 3.b4 e5 4.Nxe5 Bxb4+ 5.c3 dxc3 6.Qb3 Qe7 7.Nd3 Ba5 -/+, Zilbermints - VLT-fantonmen (whatever that latter is), ICC 2002.

The problem with 1.Nf3 c5 2.d4 is cxd4 3.Nxd4 d5 followed by e5. All that black has to know is that he must not allow the Bg5 pin, so he always has to play h6 before Nf6.
As a result white is a tempo up on a rather unpopular sideline of the "Grünfeld", so it is not clear if that is really a gain.
Exactly. Black
wants to trade his c-pawn for White's d-pawn. If White wants to take up the gauntlet, his best way is 2.e4 with 3.d4 to follow. Otherwise he can weasel around with 2.c4 and try to prove += after much machination, something I doubt he can do, though there are those here who are confident.
Here's some metatheory for you. In general in chess, the more closed the position, the less the tempo is worth. So 2.e4 must be a better move than 2.c4. Facile perhaps, but worth consideration.
VLT-fantomen is a clubmate of mine. VLT is the paper he writes for. Fantomen is swedish for The phantom.
