Custom model face culling.

I think lot of people has come to this problem: you make a resource pack with custom models, and you can't replace a your custom model with - full block, slab, carpet... -and that is real pain for those people that don't know how to code in java like me, or those who just don't want to use forge or mods because they want to use only RESOURCE PACK.

I think there should be an option in the resource pack that allows you to change the face culling for certain blocks, so you can put your custom models into game. I would love to have that option in a resource pack.
