Then we get:

FEN= 8/2pPKPp1/3N1N2/3PkP2/2P3P1/2P1p1P1/4P3/3RQR2/

w: Pd7 Ke7 Pf7 Nd6 Nf6 Pd5 Pf5 Pc4 Pg4 Pc3 Pg3 Pe2 Rd1 Qe1 Rf1
b: Pc7 Pg7 Ke5 Pe3

#1

and everything is fine:

1. No solution in the initial position (even if the 9-pawn illegality is ignored)

2. No trouble with WTM and pawn capture balance issues after removal of any of the
   white pawns.

3.
-Pd7:    1. Nf6-d7+
-Pf7:    1. Nd6-f7+
-Pd5:    1. Rd1-d5+
-Pf5:    1. Rf1-f5+
-Pc4:    1. Nd6-c4+
-Pg4:    1. Nf6-g4+
-Pc3:    1. Qe1-c3+
-Pg3:    1. Qe1-g3+
-Pe2:    1. Qe1xe3+

9 different mates.

Best wishes,
