Thanks for the good wishes.  Since I am the old man, I suppose I can try to 
answer these questions.

Yes, it seems the promotee can be diagrammed on a square other than the 
promotion square.  The statement that "the promotee may be captured" simply 
emphasizes the possibility.  Twins, etc., are welcome.  (Remember Michel's 
triplet in the StrateGems 1st TT?)  As to fairies, just remember that judge 
is a fellow with an aging mind...

Here is one lovely example in the literature:

Satoshi Hashimoto 2nd Pr. Problemesis 1998-2000

1.d4 Cc6 2.d5 Ca5 3.d6 c6 4.Dd5 Dc7 5.d×c7 d6 6.Dh5 Fe6 7.c8=F Fb3 8.Fh3 b6 
9.g4 0-0-0 10.g5+ f5 11.g×f6 e.p.+ Rb7 12.Fc8+ T×c8
    

Best,

Gianni
