Add to that the added complexity that you would like to have a window function before you DFT/FFT. Turning a FFT into Allan deviation or the reverse is among the lost causes. Also, there is only a small overlap of interest mostly, so I think they are best handled separatly, except when analysing spikes in the Allan deviation.
