[dm-crypt] Is partial LUKS recovery possible?

I'm hoping to get directions with a 'small' recovery task.
Given a partition that's known to be a broken LUKS one, lhdr is missing
(incl magic, chipher, hash, uuid, etc.), however there are some facts known:
- chipher: aes-cbc-essiv:sha256
- keysize: 256 bits
- offset: 2056 sectors
- most importantly: we have the master key file available.
I have the suspicion that the first approx 10% of the partition have
been overwritten with random data.
What are the chances of recovering any data in the given scenario?
Thanks in advance,
