[FT] scenario ideas for big ships

I'm putting together a game for 6 players, who have one or two FT games
under
their belts, and want to play with the _really_ big ships.  I've got
enough
NAC and FSE ships for about 15 a side, say 4-5 Superdreadnaughts,
Battledreadnaughts, and Battleships, 2-3 Heavy Cruisers, 2-3 Light
Cruisers,
and 5-6 Destroyers a side.  Any ideas for a plausible scenario other
than the
old come in on opposite sides of the table and fire away?  My table is 6
by 8.
