Subject: Union mount of block devices?

Hi all,
sorry to bother the ml but I'm not able to find the answer via Google.
Quick answer: is it possibile to stack block devices as union
mount? Something like /dev/sdb1 (ro) below /dev/sdc1 (rw)?
Long story...
I've got a partition with the begin of the journal over a few bad
blocks (by the way, it's NTFS but it doesn't matter), so it is not
possible to fix/replay journal, and so on.
I can dd/dd_rescue the partition to file/partition and fix/recover
all, but I just need to suck some files, so it would be a lot
easier/quicker
to stack a good partition (rw) over the bad one (ro).
Thanks a lot for your time,
Andrea
