I've tried that and you still get about 100% storage overhead.

So what is the undocumented BIF?

Maybe you should first try the suggestion by Paulo Almeida above? That is, use an array (as provided by the 'array' module) to store big integers in.
For instance, each entry in the array could could store an integer that can hold 256 bits. That would most definitely be an improvement over using binaries and might work good enough to work in your application.
