Я попробовал. Получаю при запуске этой версии ошибку:

ERROR: CheckProofOfWork() : hash doesn't match nBits
ERROR: CBlock::ReadFromDisk() : errors in block header
ERROR: LoadBlockIndex() : block.ReadFromDisk failed
CACHeCoin: Error loading blkindex.dat
CACHeCoin: Error loading blkindex.dat
Flush(false)
blkindex.dat refcount=0
blkindex.dat checkpoint
blkindex.dat closed
DBFlush(false) ended               9ms
StopNode()
Flushed 0 addresses to peers.dat  2ms
Flush(true)
DBFlush(true) ended               0ms

А если удалить blkindex.dat, то:

ERROR: CheckProofOfWork() : hash doesn't match nBits
ERROR: CheckBlock() : proof of work failed
ERROR: ProcessBlock() : CheckBlock FAILED
