Can't implement interfaces, they're all marked as classes

[PureDark]

I am trying to hack a game that's using LWRP,
By implementing interfaces like IAfterTransparentPass, it would've been easy to inject your own pass into the render pipeline
but with IL2CPP Assembly Unhollower, I can't really do that, cuz it won't allow inherits from both MonoBehaviour and an interface marked as class
