Just a little check on the mathematics, if you were to take of into wind ( normal practice) and say the wind was an average 15 knots at ground and given some shear say 18 knots at 500 ft.

So a take off at 60 knots will give a ground speed of 45 knots and then there is an acceleration to climb performance as the aircraft accelerates, then silence at 500 ft, now you have to contend with a turnback to a downwind of initial say 18 knots and if you make it on final of 15 knots into a very shortened available bit of runway at a ground speed of 75 knots assuming the approach was stable at 60 knots.

You are most assuredly in test pilot country, if you make it onto the runway , then you have to stop using a well out of spec braking system and potentially difficult runway surface.

On a 1000 metre bitumen runway this would be hazardous in the extreme, onto an 800 metre gravel ungraded strip tantamount to suicide.

This is all without considering Density altitude which could cramp your style much further and considerations of whether or not you are close to AUW.
