Combining halves of different building blocks

I think many players have thought about such an opportunity in minecraft, because such a concept does not go beyond the vanilla game, but only modifies it. Fundamentally, there is nothing unusual - the same as with the same half-blocks, but only in this case, be it stone or wood, we get a solid block with a combined texture. At the conceptual level, you only need to draw many (x2) technical blocks for all occasions.
