Please can you describe exactly what you need?

I will not accept any patch in dmcrypt which bypass encryption,
but I think the problem is solvable using combination
of dm targets, or  using some trick.

But I still have no idea what problem you are trying to solve...
(Please do not describe implementation, describe the problem.)

Thanks,
