I'd kinda hope not!
The legend that was Led Zeppelin can stand for all time in the masterful body of work the four members produced together in that era. That fact that it ended permanently adds to the whole aura surrounding the band and the music! Anything they tried now would be compared to that and would suffer as a result IMO!
I would love to hear what the 4 of them could come up with now, but seperate it from Led Zep. Allow it to stand or fall on it's own merit. Don't dilute the new stuff by trying to stand alongside the old, and don't sour the memory of one of the biggest bands of all time by trying to live off the legend.
The people who would be interested know who they are, they don't need be called Led Zep to make people aware!!
