Markdown is pretty good as a lightweight format, but if you already know latex it's not going to be a huge improvement. If you care about fancy output then it won't be as good, but you can output to html with you're own css. There is a vim plugin for org mode syntax, just with very little of the functionality. IME with workflow tools you've already hit the 90% functionality with 10% of the work part and trying to chase that last 10% actually results in poorer solutions.
