Regarding the pod:
Based on how it currently looks, have you given a thought to making a "pod-like" vessel that can detach itself from the main ship?
I'm thinking instead of the customary "secondary deflector" on the saucer, make the second deflector a part of the "pod". Equip the pod with impulse engines (which it looks like it has already), a couple of phaser arrays and 2-3 torpedo tubes. While attached, it functions as an augmentation to the weapons array and speed/maneuverability of the mother-ship. When detached, the "pod" would not have warp capability, but be a real threat to larger ships (sort of like a large combat-oriented shuttle/runabou).
EDIT: Additionally, i'm with Starforce on this one. Would be nice seeing a couple of different "pods" for specific purposes. The idea of an assault vessel "pod", would certainly be useful in hostile situations.
