Resistors have real impedance and capacitors and inductors have purely imaginary impedance so you can't bridge those two domains (it's like saying can you make a complex number by adding/subtracting real numbers). For capacitors and inductors one have an impedance that increases with frequency and the other has an impedance that decreases with frequency. So for a given frequency they are interchangable, but as soon as the frequency changes that breaks down.
