A Certain Block Could be Used to Give Sulfur Slimes Physical Hit Boxes

I love the sulfur cube idea, and with a variety of combinations possible for it, it was strange that not a single block (like iron) gave them boxes that were impactful to the player. What I mean by this is that if Minecraft is already incorporating weight with distance traveled (You hit a wool block, it goes further in comparison to an iron block, sulfur slime), they should incorporate their hit box force to the player. For example, an Iron Sulfur slime would forcefully push the player, and a wool infused sulfur slime would simply bounce off. I remember someone describing the slimes as bouncy balls in Minecraft live, and this would make it more realistic. And it's just logical. If you're going to acknowledge input force, then also incorporate output force. I'd really like this to become a feature. Ask any questions if you need clarification!
