I don't know what a dropped 2 chord is.

It's probably a dumb question but here's the point: For guitar players, discovering dropped D tuning is like a "Eureka" moment. To quote Neil Young (I think it was): "It changed my life; I've never been the same." It's just a very cool sound.

So, if there is a way when playing a song, especially with guitar in it, if there is way to capture that unique sound. But I doubt there is. It's a guitar thing. You get the low bass note and some complimentary ringing due to the lower pitch or whatever that term is... other strings ringing in a different way.
