Jackson would have probably noticed that taking Big Round Top not only flanked Little Round Top but the whole Union Army. Stonewall wouldn't have needed Stuart to see that.
Taking Big Round Top would have unhinged the right and center of the Union line.
GEN Jackson would have thrown 4th Aabama back into the fight. Chamberlain's MAINE-iacs were BRAVE but nearly out of ammo. had we taken out 20th ME, the army of the potomac was TOAST!
