Maximummer: Black must play the geometrically longest move or may choose from among longest moves of equal length, distances being measured from the center of each square. Diagonal and oblique distances are measured from the orthogonal coordinates by using Pythagora’s theorem (take the square root of the sum of the squares of the orthogonal distances). All other orthodox chess rules apply.

Happy New Year ! 🙂
The funny idea is not new, it even has a name: Raindrops Theme. You can see the (black) raindrops falling from the 7th rank!
One example with 7 raindrop variations is this (WinChloe #28793):
Wilhelm Massmann, Pr. Die Schwalbe TT 1953-55
Kh1 Qh2 Ra4 d8 Bb1 Pc2 c4 d3 e3 f4 h6
Kf2 Qh8 Ra2 g2 Pa7 b7 c7 d7 e7 f7 g7 h5
s#3 Max C+
1.Rg8
1. – a5 2.Rxa5 Rxa5 3.Qxh5 Rxh5#
1. – b5 2.Ra8 Qxa8 3.Qxg2+ Qxg2#
1. – c5 2.Rb8 Qxb8 3.f5 Qxh2#
1. – d5 2.Rc8 Qxc8 3.Qh3 Qxh3#
1. – e5 2.Rd8 Qxd8 3.Qh4+ Qxh4#
1. – f5 2.Re8 Qxe8 3.Qxh5 Qxh5#
1. – g5 2.Ba2 Qa1 3.Qg1+ Qxg1#
1. – Qxh6 2.Qxh5 Qa6 3.Qh6 Qxh6#
1. – Rxa4 2.c5 Rxf4 3.Qh4+ Rxh4#
1. – Rxc2 2.c5 Rxc5 3.Qxh5 Rxh5#
There are also others with 5 or 6 raindrop variations and better economy than Massmann.
Only 6 variations here. 1..a5 allows the threat.
Not quite. There is no real threat. 2.Rxa5 works only after 1…a5, even if there is no defensive error in 1…a5.
