Earlier this morning, I was looking at this Chess Stack Exchange Question, although the question itself isn't relavant to this post: https://chess.stackexchange.com/q/5888/15543
What is relavant is this: @CSE user Fate, the asker of the question, had created the below problem that the question shows
WTM, #23
 (= 10+18 )
While the mechanism seen in the solution is ingenious for an easy more-mover meant for amuarter solvers, the unfortunate thing is that position is illegal. The creator be even admitted it themselves.
However, while mulling over how I could possibly improve economy of the position, I struck gold. I had a magical moment of insight, a flash of amazement, and a dash if adrenaline. With a single White knight and pawn, I murdered that horde of Black pieces and made the problem legal!
Rewan Demontay, After CSE User @Fate
WTM, #23
 (= 11+10 )
While the solution has many, many duals, it is now much more acceptable with the above legal position
This made me wonder: What are some examples of such famous inprovments to the legality, economy, and/or promoted piece usage of a well-known problem that uses a particular idea/theme/mechanism?
The first thing that came to my mind is how this problem (both ripped from Wikipedia);
Pierre Drumare
Memorial Camil Seneca, 1980
 (= 15+15 )
Became this (ignoring how this itself was later Improved):
Leonid Yarosh
Shakhmaty v SSSR, March 1983
 (= 13+10 )
There's also how the cycli Babson was e eventually done without any promoted pieces
What are some other famous examples of fampus Improvments?
P.S. The Wiki says that Drummare made. a Babson with Nightiders. Does anyone know of where it could be found? I've read it as
mentioned but never has it actually been shown to my eyes.

Famous it ain't, but some poor git leant himself out
of the window by commenting that Dawsons "switchbackery"
(White takes back a double step and plays it again,
as he wants the e.p., but can't prove legality of it
in the position) would be "impossible in miniature"
(it has 9 pieces). I was young, I was a bigmouth
(no, wait, I STILL am a bigmouth :-), I had it done in
five minutes :-) (SCHWALBE 98, 1986 Nr.5464)
EDIT: What does the Pa7/Pa6 pair do? If it could stand
legally on h7/h6 (didn't check), you might gain a
few moves (didn't check either, a premature Bxg6+
might cook it).

1.Bf1 Bg1+ 2.Sxg1 seems to be a problem. The knight heads up to a7 and White queens on move 9.

Hauke, those pawns are there to presumably extend the length.
And golly gosh, you are right Geir. Once White Queens, Stockfish announces a mate in 7.
Cook:
1. Bf1 Bg1+ 2. Nxg1 Kxg5 3. Nf3+ Kf6 4. Nxd4 f3 5. Nc6 Kf5 6. Nxa7 Kf4 7. Nc6 Ke3 8. a7 g5 9. a8=Q g4 10. hxg4 Kd2 11. Qxa5+ Kc2 12. Nd4+ Kb2 13. Qb4+ Kc1 14. Qc3+ Kb1 15. Qc2+ Ka1 16. Nb3#
Well that sucks.

I suppose what I CAN do is to improve the position'a economy, even if it is still illegal.
