Hi and welcome Adele, but sadly I‘m not a bearer of good news.
Near impossible is pretty right, even if you got the board, the features of the Surftech construction may not be able to be done by a shaper.
The differences in the EPS versus PU foam makes different density and flex patterns along with the epoxy versus polyester resins.
I would look seriously at Randy Frenches current shapes at Surftech or other shapes similar to what you want in known brands.
This would also be dependent on which country you are looking to buy in!
Added edit, can you post a picture of your dear departed, then we can suggest possible replacements of similar construction,
some good news ( perhaps) there may be performance improvements in newer boards!
Good luck!
