Good thing grandkids are around when it comes to our technology deficiencies, I guess!
The 225 springs may not work, as the narrower coils at the top of the spring are normally there to fit inside a synthetic follower. From what I observed from the generic parts breakdown, it appeared the follower was steel, as the 225 follower was, and photos also appear to agree it's steel.
I'd try trimming one of the Wolff springs to the same # of coils overall, and seeing if it will work. You may lose a round of capacity without trimming the spring, or it doesn't fit behind that front "shelf" of the follower that engages the slide stop, but it would keep the nose of the follower "up", preventing "nose dives".
Good luck with your experiment!
