They are but unless you are willing to spend a lot of hours (or money) mapping it to run nicely it would be cheaper to stick with the L8, ford spent A LOT of money developing them to work properly in all conditions.
I've got an SM4 and I've spent a lot of time making it run as nicely as my old super8 did, for your average punter it would not be worth the effort versus the features you gain.
