Well both yes an no. Your suggestion works for me but not for my client (the end user). To be able to push the job of bundling things to the client the solution had to be even more trivial. He/she does not know how to create a size.bin with the correct content and endian.

That's why I seeked a more reliable solution, when it comes to assigning numbers properly I do trust the vc linker more than any human.
