Spelljammer - Treasure Planet Style!

There's some discussion going on at the message boards about doing SJ like
Treasure Planet.  You can find it at:

I thought I'd get some discussion going to see what people thought of a
Treasure Planet-style SJ game.  I'm not referring to anything official so
much as I am just an alternative to classic SJ.

To me, the key thing is to have that 70/30 ratio of fantasy space and
technology, which they sort of refer to on the Treasure Planet DVD.

So, what do you guys think of this sort of setup?
