Could the shuttle go up just as well using paraffin/kero and lox the

The SRBs might have to get somewhat larger, because the gross liftoff mass
of the orbiter plus ET would be higher. On the other hand, the ET itself
would get smaller and lighter (heavier when filled, but lighter when
empty) -- it's currently mostly LH2 tank.

Or the same size ET would hold sufficient dense fuels to supply
liquid booster engines also, eliminating the SRBs.
