Even if the whole premise is a good idea, as a mere SLF I don't understand why you'd want to build in the additional equipment (= weight) to the a/c when a perfectly good tug would do the job instead.
In any case, I always understood there were sound technical and safety reasons (not to mention it being good airmanship) why you warm the engines up away from the runway before turning the volume up to 11 for t/o?
