I don't believe it would be possible to do it but, is it?

If I was to use say a full frame 50mm lens on a 2x teleconverter with a 0.71x focal reducer on APS-C would it work? Would you also get the benefit of an extra stop of light from the focal reducer?

Thanks

Can you use a focal reducer with a teleconverter? I don't believe it would be possible to do it but, is it?
