if they have no hets they would produce normals het anery amel hypo stripe, you would need to find out what the parents were to find out for sure what you would get from this pairing.
ghost stripe (parents both ghost stripe) x ghost motley (parents ghost stripe x anery motley het hypo)
sorry for being a pain.. its just insatiable curiosity :p
that would give you ghost stripes and ghost motleys. The 'stripe' look of some motleys is independent to a snake being het stripe so as always with motley the pattern can be very unpredictable.
