Tusk as two single LPs vs a double album?

[SortaSavageLike]

Now, I'm sure we all know why Tusk kind of, uh, stiffed way back in 1979. Double-diget inflation, high price, mixed reviews, so on.... What if it was released instead as two single LPs, the first in late 1978, the second in mid-1980? Would it have sold better?

Just for giggles, I've attempted to pull together a track listing for the two albums.

Tusk (11/78)
Side A
1. I Know I'm Not Wrong
2. Sara
3. Save Me A Place
4. What Makes You Think You're The One
5. Never Make Me Cry
6. Tusk

Side B
7. Brown Eyes
8. Think About Me
9. Angel
10. Honey Hi
11. Sisters of the Moon

That's All For Everyone (08/80) (Okay, that was a gag title, and I'm not that happy with this one because there's only two Christine songs on it)
Side A
1. Never Forget
2. Not That Funny
3. Storms
4. Kind of Woman
5. That's Enough for Me
6. Walk A Thin Line
