An 8-bit adder with only Generate

Hey guys,

i am new to this but is it possible to design an 8-bit adder with output to be Sum0 and Sum1 [depending on Cin0 or Cin1] but only have generate signal in it and not a propagate?

So toplevel would have two 8-bits coming in as A[7:0] and B[7:0], the output would be Sum0 and Sum1 [depending on a late arriving Cin of 0 or 1]. one more output is going to be G.

Thanks,
Mike
