Is it possible to get the same 2:1 magnification with a longer working distance?

Re: Is it possible to get the same 2:1 magnification with a longer working distance?

I have recently been experimenting with a 2X teleconverter on a Laowa 100mm 2X macro lens. This gives a working distance of around 90mm at 2:1 and around 70mm at 4:1.

With a Raynox 250 on a 55-250 at 250mm on a Canon APS-C 70D I get a maximum magnification of around 1.9X with a working distance of around 120mm.

With a Raynox 250 on a small sensor FZ330 bridge camera, at maximum magnification I get a scene height which would need 2.5X magnification on the 70D, with a working distance of around 120mm.

The first four of these were captured with a 2X teleconverter on the Laowa 100 2X macro lens on a Sony A7ii. The last two used a 2X teleconverter with a Sigma 105 1X macro lens on the A7ii.
