Please allow a block to be placed "inside" of a Mob Filter Block, changing it's appearance.

This would be done by sneak-right-clicking with the block being used as a disguise; if there is already a block inside the Mob Filter Block, it would come out.

Sneak-right-clicking a disguised mob filter block with an empty hand takes out the disguise entirely.

Inverting an undisguised mob filter can still be done: sneak-right-click with either an empty hand or a non-block-item in hand.

Inverting a disguised mob filter can also be done: sneak-right-clicking with a non-block-item in hand.

Also, the copycats module does this, it's the main purpose of these blocks to take on different textures.

This would be an amazing addition ^.^
Tho considering this suggestion has been sitting here for 1.5 years. Assume we'll never see something like it :/

I would love to add this to the mod which is why the issue is left open. Modders just don't have a good way to do this at this time.

Would a possible solution be to integrate with the Transparent mod? Then maybe we could sneak right click with say a glass block to turn the mob filter transparent?
That wouldn't be exactly the same thing, but would allow folks to make more pleasant looking builds

I don't know if you're able to use the same technique but the OpenBlocks Elevator block allowed you to right-click another block onto the elevator and it would take on the appearance of that block.

I'd rather have normal rightclick disguise the block, similar to every disguise block
