Do you mean use artifically high V speeds by using a higher weight for the calculation
Make believe weight increase to give a sensibly calculated higher speed schedule. Caveat is that one needs to make sure that the AFM doesn't preclude such a procedure (which I would not be expecting to see).
As noted, the other concern with short ferry flights is that the low speed schedule brings you down into the area where the effect of cross wind on the real world Vmcg is worth considering .. pushing the schedule up to account for a notional delta might just avoid some sweaty palms if one goes quiet during the takeoff ...
so I don't think about such things much anymore....
Takes me back 40-odd years to the silly things we used to do in SuperCubs to impress the ordinary folk in Cessnas and other such mundane hacks ... a touch of head wind would see the bird leave the ground somewhere near the end of the piano keys ... all very silly viewed now with the conservatism of years .. but it was great fun at the time.
