no way, so you 3d printed a shorter spacer? or is it a longer spacer? would you be willing to make another and how much would you charge? i was thinking it needed a whole new airshaft like the 29er rebas require. could i

If you look at the pic, the stock hard rubber spacer is on the left, that shortens the fork 20mm. I added the middle spacer, that reduced the fork another 20mm.
I mean I could help you, if your air side is identical, no problem. You could save time and money and have a local library or maker space print one. I used PETG but I doubt it matters much.
These reba dual airs are pretty sweet. After reducing the length for a 24" bike, you can either shorten or remove the spacer, which I did so it's a 120mm fork for my kids 26" bike.

What I was thinking was reducing the stroke length so that both lower and uppers could be shorter, to minimize the overall length and allowed a lower front end

It reduces the overall length. Rockshox sold the spacers years ago, it's a documented thing.
Ludo:
That’s a great, I didn’t realize that! Opens up things nicely then, off to find a good 26” fork then
Ludo:
Can the same be done on more modern 26 reba like the SL?
