You mean you sdc and sde plus either sdb or sdd, depending on which one I think is more sane a this point?I'd try both. Do a ddrescue of the failing one and try that (with copy of the others) and check what's coming out.
As an alternative to using ddrescue, you could quickly prototype various arrangements (without writing anything to the drives) using a device-mapper copy-on-write mapping - I posted some details to the list a while back when I was trying to use this to reconstruct a hw raid array...
