Ya, damn Germans...my family too
When you get the new fork, any chance we could chat dimensions etc. There has to be a reasonable solution for both the slippers and the square guidance piece. In all the vids of teardowns I have seen the guide piece is only ever broken on the bottom...and in most cases only cracked. I think the only solution there might be to form and fit a replacement to the lower edge only.
It's not the cost of replacement that is a barrier, I just like a challenge and this, by all accounts, should be a fairly straightforward and doable. I mean c'mon, I have two part metal epoxied a hydraulic housing underwater and it held...somewhere on the shelf of cans I have has to be an adhesive that will hold a piece of plastic/bronze to a piece of aluminum LOL
