D47 is a good yeast. I've used it in a few brews and have liked the outcome. Plus it is a good yeast to age sur lee (on the lees). So you really don't have to worry about racking right away.
I needed my carboy free, so I racked/bottled mine right away, but I've read that it adds a little bit of a buttery mouth feel to the wine/cider. You'll be getting some decent body with the 1 gallon of juice and 1 can of concentrate as well. Hope it all turns out well for you... let us know how it goes!
