Hey there 
This is certainly a nice idea, but sadly isn’t something that we will be doing.
Bedrock is a very different platform to Java, in that we have to cater to players playing on a wide range of devices, including mobiles and consoles.
Some of our Java games, therefore, just wouldn’t fit on such a platform. We’d also much rather innovate, than copy all of the games that we already released several years ago 
This being said, we may adapt certain Java games, BlockParty for example is on our roadmap
