There was one beautiful problem of this type by K. Hannemann, CPDB problem number P1082699:

 Knud Hannemann ,  Dagens Nyheter,  1933

Mate exactly in 1, 2, 3 and 4 moves.

The four solution present one very nice theme. 
I suggest that the first moves be stipulated to be different from each other - otherwise, it doesn't seem difficult to take n to about 50 (this boundary only exists because of the 50-move rule) by restricting severely White and Black's moves, so that White can only play a mating move or a waiting move on every step, and Black can only play waiting moves.

Best wishes,
Nikolai
