Can I daisy chain Thunderbolt to FireWire 800 to FireWire 400

If I had a FireWire 400 DVD drive connected (via a FireWire 400-800 cable) to a FireWire 800 hard drive that was then connected via a Thunderbolt to FireWire 800 adapter to a Thunderbolt hard drive, that was then connected to a Mac, would I be able to use all the drives? And would I get Thunderbolt speeds on the Thunderbolt drive and FireWire 800 speeds on the FireWire drive? Also all the drives are powered externally.
