Just make the current one clickable, and I'll be happy.
The concept one is pretty, but functionally it might not be the best choice. For one, it can't be to scale, obviously, but for some systems it would be very misleading. And many would expect such a view to be correct in regards to the orbits as well, so there's more calculations and inaccuracies to deal with.
I like the one we have because it presents all the data right there, shows the relationship of the objects simply, and actually teaches a bit of astronomy in order to be able to use it fully (as in, what do all those numbers mean?). And that's not a bad thing.
