Is it possible to run WSL shell as the FileName?

Description

I've tried several variations to run the Windows Subsystem for Linux shells from CommandTaskRunner and have been unsuccessful. All variations so far either crash visual studio, say 'wsl' is not recognized as an internal or external command..., or produce an error dialog.

Steps to recreate

Try any of the following as the FileName+Argument pairs in a new command in commands.json.

wsl
wsl.exe
cmd /C wsl
cmd /C C:\windows\System32\wsl.exe
cmd /C C:\windows\System32\bash.exe

If any of these produced a bash shell, or executed a .sh script inside that bash shell, it would be sufficient. Most of them work just fine if I run them from command prompt, but something about the way it's implemented in TaskRunnerExplorer makes them all fail. Perhaps someone who understands TaskRunnerExplorer internals might be able to imagine a working incantation.

Of note, some tutorials I've seen for VSCode say things like this:
add this rule to your User Settings:
"terminal.integrated.shell.windows": "C:\WINDOWS\sysnative\bash.exe"
