I don't think that it makes sense. First of all, it can be really time-consuming task. From another point of view, it will be really slow solution. And I don't think that it will be simple to port this code base from one ideology to another. Moreover, it is not interesting task for me personally. :)

As I remember correctly, we had discussion about this issue. I tried to reproduce such situation but without any success. Every volume is created by mkfs utility. So, if it is impossible to create volume with such anomalous layout then it is a volume corruption. Could you share the way of creation such HFS+ volume?

Thanks,
