FS1 capship battles are fine, they need some visular polish (adding trails to the THT, VHT and SMT does it) but otherwise not much to change there on the table side ... sprincle in some cruiser support (Fusion Mortar FTW) and it looks good
Now bombers on the other hand need a little love in a reimagining of FS, away from the dive bomber style to something more akin torpedo boats or somthing (all FS1 era-bombers, exception for the Athena and the Zeus) are already patterned with a "flying fortress"-design in mind, esspeically the Osiris and Amun
But what I would want most off all: MAKE USE OF THE SD DEMON! and not just as a big target, the Demon can be made to look awesome (see ST:R)
