K64 SDHC interface with emmc device

The K64's SDHC states that it is compliant with MMC System Specification 4.2/4.3


I am looking into interfacing the K64's SDHC with a emmc device meeting specification 5.1.


I would like to use the 8 bit data interface.


I have not been able to find any information as to interfacing a 5.1 device with a 4.3 version controller.


Can this be done? 


What are the pro/cons associated with an "old" SDHC controller mating with the latest emmc devices.


Thanks in advance for any replies.
