Java mods on bedrock or java compatible with tablet/controller

Playing on a tablet and watching the java mod: create, is just making me beg to have support on tablet, since java and bedrock use different engines, maybe you could make java have mobile/controller support. You could add minecraft launcher to the play store (or any mobile store) and all the console stores. The easiest thing you can do is make bedrock able to use the java engine with a setting, this should not change anything about bedrock edition, just the engine from bedrock should also be on java edition, also toggled by a setting.
