It does not make sense.
DS is not only dead - it actually never existed. It was a vehicle to play Mark Knopfler's songs, period. Which is exactly what MK's band is today, except that this is more frank, and have the advantage of not creating huge expectations in terms of touring scale and "soft rock" style of music. Nothing more than a marketing label. On the documentary on the Alchemy DVD, MK is asked (1980) if this is really a group, as he is the main writer, singer, and performer. He answers that it is all about the band and being together; might be true, but this is also true of his current band...
The only thing you don't have anymore is the name - who cares about the name ??
I am amazed the impact a simple label can have on people. in 1987 Roger Water's tour was completely destroyed by Gilmour's Pink Floyd touring. Because everybody new the Pink Floyd name, and nobody but the die-hard fans had ever heard or Roger Waters. In fact, they were seing the band as an entity by itself, not the people the band was made of, and the vast majority of them didn't even know that the soul of Pink Floyd was gone. Gilmour said that he spent 20 years building the Pink Floyd name, not his own. That is true, but that is scary.
Hence the ridiculous stickers they had to put on the solo CDs: "the voice and guitar of Dire Straits", "The voice and guitar of Pink Floyd", "the soul of Pink Floyd", etc.
A Pink Floyd reunion made sense beause to build PF you need BOTH Gilmour and Waters; but MK has everything in himself that Dire Straits had; because the other musicians, although world-class, are disposable items, not unique; John Illsley is a fantatisc bass player, but so is Glenn Worlf; Same with Alan Clark and Matt Rollins. In fact, the band is more stable know than in DS times...
Come on !! Move on !! It will not happen anyway. Everything DS would have to offer today, you already have it in the MK shows.
