Weight tweaking to increase max virtual power

My dumb trainer (Tacx Booster) has a max power of 1050 Watts. However with Zwift I can only get to 380 Watts with the recommended resistance level 2. Then I run out of gears/rpm. What will happen if i put it at a different resistance level en change my weight like this:

 

Has anyone tried this (or something similar) in Zwift? 

Hi Harmen,

that is a nice idea. Did you test it and does it work?
