Calling All Science Fiction Oulipians!

John Holbo at The Valve has taken a look at Hugo Award category definitions and said:

...science fiction lacks anyone with an Oulipo-streak. Imagine a collection of short stories each 7,499 words. By definition, they would not be novelettes; but what if they were paced like novelettes? What if two of them were interconnected—same characters, different times—would they now be a 14,998-word novelette? Would three be a 22,497-word novella? Six a 44,994-word novel?

We here at Mumpsimus Central are fans of many different sorts of streaks, including any Oulipian ones, and I'm sure we're not alone. Perhaps some of you out there will take John's statement as a fun challenge...
