Adjustment for physics

Can you add new physical functionality to scripting api. It will be cool if modders(authors of add-ons) can add multiple collision boxes to their entities for example. Maybe modders can add movable structures or something like this. For developers: if u want to add it to Minecraft bedrock u can watch something helpful in java mod sabel to add sub levels for Minecraft bedrock in it's engine(on c++) to give it for modders in scripting api
