Everything looks pretty good. And while I don't think the sublight drives are so much a problem in terms of diversity as the all-purpose quantum reactor, new ideas are always good . I don't like the displacer though. Brickwarping combined with guaranteed prizing of bricks is an exploit of the game. We should be discouraging it, if anything. I would not mind it if the displacer is made to be a shark-exclusive item, and antideath bricks eliminated. Getting instantly knocked out of a base by someone who's completely invisible is one of the most game breaking things ever. Also, unless the spread bombs are coupled with either ridiculously high energy cost, or a slow rate of fire, they would be extremely overpowered in a base, as a single falcon missile spammer can already flood the area with shrapnel.
