A much needed shield update

You now how In java you can put a banner on a shield (I think that should be in bedrock and you should make bedrock exactly like java) well what If you could place a map on a shield it would be perfect for role plays and for those that convert an irl image to a minecraft map it would open so many doors for designs and so much more plus it would give maps more than 2 reasons to exist imagine having our favourite little redstone engineer and builder having a little mustache on there shields or dantdm having a picture of his scientist friend on his shield me and 5 other friends are making an smp and I'm posting it on YouTube it would be a so needed update plus maybe adding a few shield enchants other than unbreaking and mending like a type of thorns or a higher knock back enchant when someone hits it with a sword or an enchantment that makes it harder to send it into cool down the shields are just that shields but minecraft has some many functions for items that it doesn't seem right to just slap it on the off hand and left click just to block one attack and not really have any other advantage than that heck you have given iron the ability to summon a litterale body guard everything in minecraft has more than one use but shields don't,you just block them and that can easily be undone with an axe or pressing w they need something that can make them better there basically useless right now and need an upgrade like its own enchants thank you for your consideration
