Is it possible to create a software RAID 10 using SAN LUN's presented to server on 4 paths?

Yes, the LUNs are just presented as regular block devices, that said why wouldn't you do this on the SAN array side anyway? that's the way everyone else does it - it saves 50% of bandwidth on writes for a start and is a lot easier to setup and manage.
