More Detailed Banners on Shields (java edition)

In Minecraft, you can put banners on shields, but when you do so the banner design is often lost when the design has to be shrunk to fit on the shield. This causes some problems if you want to make some complex banner-shields. In my Minecraft world, I am trying to build an entire kingdom, and while I was designing the flag of the kingdom I remembered that you can put banners on shields. You can imagine what happened next, I tried to put the banner on the shield and the banner looked different. I suggest making the banner pattern have smaller pixels on the shield so the whole image can be displayed. This would greatly improve the potential of banner-shields as a decoration. This would overall - in my opinion - improve the decor potential in Minecraft. Thanks much for reading my suggestion!
