Using the Dark Elf Cold Ones for Lizardmen Instead

So how feasible do people think it would be to use the dark elf cold one models instead of the lizardmen cold one models for cold one riders?

The dark elf models are incredible. They look just like a terrifying velociraptor-type dinosaur should.

The current lizardmen cold one models look to me like the "land before time" version of a velociraptor that has been made goofier looking. This is still an improvement over the even older hump-back cold ones. "Go and waddle forth!" Seriously, any create with that much curve in the spine looks silly.

I looked at the bits, and it doesn't seem to be as easy as a rider swap. The dark elf cold ones have the saddle molded onto the cold one body. The lizardmen riders have the saddle as part of their legs. So do you guys think it would be doable to carve away the saddle and fit the lizardmen onto the awesome cold ones?
