Interesting idea, but I don't think it would be practical. And I'm speaking as someone comfortable in both the DOS/CMD world (and 4DOS/4NT!) as well as KiXtart. The problems as I see them are:

1. Handling all the switches on various DOS commands
2. Various versions of DOS/CMD/Command
3. Piping and redirection
4. Weird syntax and batch 'tricks' that some folks love to use
5. DOS extension utilities batch programmers often use for input and file system tricks

You would probably end up with really ugly code that needed to be checked by a competent KiXtart person anyway.

I'm not trying to discourage you. This sounds like a fun project to attempt, anyway. But there are some real hurdles you will have to clear to make it practical.
