I don't get what you mean,
It Seems that you'd like the plane/sim to adapt to you whereas it should be to you to learn how to fly it, real pilots tell us that the real 737 does hover a lot if the flare is not done correctly, it's up to you to learn how to do it, not to the sim/developer to change the physics.
If you try to lose weight, the correct way is to start adapting your food behavior and also to have a more fat burning activity,
not changing the Newton gravitational constant of the Earth…
