Yes it is quite possible to re-design a line output stage and replace the EHT generator with other systems/parts, but that is quite different to dropping in a substitute transformer and having it work off the bat with the existing circuitry and no other design changes. The only way to have this is to use the exact transformer.

In American designed sets, many with what are known as RF EHT generators, they suffer from similar problems with the transformers, in this case the EHT drops with time. So one solution to those has been to add in modern plastic potted EHT generators. The only thing is, its a bit of a bodge and it leaves the system far from original.
