I certainly would hope and think so, but no one really knows.
It's such a tough call to know how a show or tour would do.
The one that always comes to mind is Candlemass' last US tour, which was what, their first US tour in over 15 years? Sure, one could argue that no one cares about Candlemass sans Messiah, but damn. That tour had TERRIBLE turnouts. Were there even 150 people at the Pearl Room?
It seems the real "Breakout" bands these days are the ones that have "Hot Topic" appeal (So, for the past couple years, this has definitely been the whole viking / pagan thing).
Hell, that band Eluveitte (SP??) is headlining over 3 Inches of Blood, and Turisas are on the Cradle of Filth tour.
As much as I love MDB (and I REALLY do, they are on my top 10 list with ease of active bands I want to see live, and have been for a few years now), I would be skeptical with how well they would do.
Now, if it was part of a one night only one off, with at least 2 or 3 other bands that do not tour regularly (IE - Woods, Agalloch, ND), yes, then this would be a different story.
Back to the Candlemass example, I said it before, that I think for being away from the States so long, they needed a solid touring partner. Nothing against Daylight Dies, but they aren't what I would call a draw. They should have done a co-headlining tour with Trouble or someone of that ilk.
Sorry for the ramble. Once again, with good advance notice and promotion, and a solid lineup, yes, this show would do amazing.
