I made a small project back when WSL was new to help tackle this, called Slinky: https://github.com/cpdt/slinky/

It allows you to run a command in the Windows prompt to 'link' a Linux command to a Windows one, allowing you to run the Windows command to run the Linux command (if that makes sense; the GIF in the Readme is probably better at explaining).

It's written in Bash and Batch so doesn't require external dependencies.

You could always:

    C:\> doskey ls=bash.exe -c "ls $*"

    C:\> ls /
    bin   cache  dev  home  lib    media  opt   root  sbin  srv  tmp  var
    boot  data   etc  init  lib64  mnt    proc  run   snap  sys  usr

I think it's fine as is just so you even know/remember where you're running that command from. What's not exactly ideal is completely blurring the lines between both kernel syscalls.
