There's nothing wrong with commencing a take-off with full aileron applied, as a technique, if the conditions warrant it. Of course, as speed increases, the controls become more effective and, therefore, the amount of aileron and rudder usage needs to diminish accordingly. This is pretty much P of F 101 - effect of controls stuff.
I don't know what stage mscar is at but I suspect that the thing he/she is after will be found in the take-off performance charts for the particular aeroplane type. I recommend that he/she grabs the performance manual for any aeroplane type and run some calculations based on the same basic environmental factors but considering the following wind conditions :-
1. 20 knot headwind;
2. 20 knot tailwind; and
3. 20 knot crosswind.
I would expect that the results of this work, which should take no more than about 10 minutes or so, will yield the answers fairly definitively.
