By the way, just wanted to give you a quick picture of what is possible with the current components...

The bigger engine as suggested will be made, but will be another component, basically a variant on the engine I've got now. The current engine is for standard cruisers, the larger engine (which will be a redesign of the one I've got now, but a lot beefier) will be for heavy cruisers. Reason I'm going for this route is that simply resizing the engine component makes it look odd compared to the rest of the ship.
Besides that there will be some turret variants, prow weapons, and some new components (so you have more options than the launch bay component). It would allow you to really create your own ship designs, only limited by your imagination and ability to balance it (unless you use a way larger base, and pin it to that base on multiple spots).
