Bedrock with more options for PC players

Started using bedrock more since all my friends gone to it, I'm so use to java using a shield is very very very difficult since on java you use your mouse to block and on bedrock its your crouch key, doesn't help pc players at all, is there a plain to add a option for this for PC players? 

Also if people could make a option some how for Bedrock feel more like java, not sure how you can but I feel like a lot of old time players would enjoy bedrock more.
