It's something that has been discussed, particularly with a view to releasing something similar to the V2 Suppression system and melee changes, but because V2 includes some very fundamental changes it's practically impossible to implement while keeping any sort of meaningful balance.
It's worth mentioning though that while V2 is more streamlined than V1, anyone used to pre-8th edition 40K shouldn't have too much trouble with the level of complexity in V1.
