You seem to understand transforners :-)
I am wondering what I can do with this

If you are going to use a transformer, why use the doubler at all?

If you can't fix it, you don't own it.

24V transformers with beefy secondaries are relatively cheap and easily
available. 240-415 transformers are large, expensive and difficult to find.

The 24 volt transformers are called commonly called Buck/Boost transformers.
Oftentimes used to boost 208 to 240 volts or buck 240 down to 208..
