Sure, that's fine to me.
FWIW I tried this (adding it to the effect from the d3d10 tests):

GeometryShader v_so = ConstructGSWithSO
(
    CompileShader( vs_4_0, VS()), "SV_POSITION.x"
);

FXC seems to accept it just fine and, according to FXC itself, it
actually generates a GeometryShader object with the VS() shader inside
(as a normal vertex shader, vs_4_0 and all) and the streamout
declaration.
