[Farscape/Alien] What would happen if a leviathan from Farscape were infested with a xenomorph?

Could it happen? If so, how would it go down?

I can't see how it would be possible.  There is simply no 'face' for the facehugger to latch onto and no suitable place to implant the chestburster.  Leviathan biology is just too different from the Xenomorph's typical prey.  
I imagine a Pilot could be infested though.  Probably resulting in a very large multi-limbed drone.  It's doubtful such a drone could bond with a Leviathan.
