What if it had a special BO slot for a special BO?
Think about it this way: the Enterprise-D and the U.S.S. Righteous from Star Trek Borg and the Excalibur from New Frontier had ship counselors as senior staff, whereas "Counselor" appears to typically be a position that would be a duty officer at best. While a Counselor might fall under the sciences, we don't have a representation of that career path. Most ships wouldn't have a "slot" that accommodates a counselor.
The Defiant, early on, required the assistance of a Romulan officer to legally use its cloaking device.
So here's a couple of thoughts:
- What if the Odyssey class takes a new profession of special BO? Like a purely diplomatic BO?
- What if it has a designated slot for a specific "hero class" like a Daystrom Institute Specialist, which is a special non-trainable engineering BO with enhanced versions of engineering powers? Or what if it has a "hero class" slot, comes with one prefab hero class BO, and Cryptic launches more down the road, with corresponding Klingon refits?
- What if it has a universal slot but that universal slot has a restriction on it?
For example: maybe they introduce the Emergency Hologram station as a preloaded console. Having that console gives you an extra universal Lt. slot. You can place any photonic officer in that slot but holograms' powers all draw an extra penalty from auxiliary power. Actually THAT sounds like an Intrepid and/or a Sovereign console.
Now... A Longterm Command Hologram might be a console that gives you an extra universal Commander slot but this BO's powers have both an auxilary and tactical energy tax.
Could provide a fun mechanic... and a way to use lower tier ships at higher tier levels, with an obvious penalty that requires close management.
The Odyssey, well... It might be cool as the first ship designed to have a longterm command hologram, something Starfleet was always moving towards, With the awareness that the universality of the slot has a power level penalty that requires playing the ship differently.
Holographic officers could go in any slot that corresponds to their profession, like the current one we have is a normal science BO, under the assumption they have mobile emitters, which is assumed when they beam down.
However, say there's the introduction of a magenta-colored slot with the Odyssey. A magenta colored slot represents a hologram being loaded into ship's memory. It's a universal slot that can only be filled by holograms. Any hologram stationed to this slot maybe gets a boost to certain kinds of powers (for example "team" powers, all buffing powers) but their powers have an auxiliary energy tax. (Because the computer is "storing" them.)
The Odyssey would be the only ship with a Commander level magenta hologram slot, representing that it's designed for holographic commanders.
However... The devs could go back and rework the Sovereign and Intrepid to include Ensign (for the Sovvie) and Lt. (for the Intrepid) hologram slots, or design variants. Which would make those ships more interesting and appealing when compared with the "superior" ships of other types introduced since like the Excelsior, reflecting that those two classes were designed with EMHs in mind.
