Hi
It's an interesting notion, but one that'd take a huge amount of work, and would most likely impact too much on performance.
At the moment I'm too busy to undertake any investigations, but if you want to have a go, I'd be interested in the results.
Of course, if you absolutely must have it, you could sponsor the work for a library extension. :-)
