How about changing concept from current around-core-interior-part to solid template monoblock with only outputs to ship systems(red alert, emergency lockdown, etc)? Most of the ships have core rooms/bridges with their unique design, and your room space and elevator may be just not needed. At the same time, if computer get update with new functions, it will be easier to remove whole old block and paste new without need to change any interior designs and with only few minutes work of connecting logical outputs to ship's systems and refreshing displays content.
About functionality: maybe integrating Thalanor's systems graphs for possibility to display a holo-screens with complex ship information on bridge? They can include displaying current chaindrive program, ship's own usd-docks states and many other custom things. It's also possible to print alert messages about detection of active jump inhibitor nearby and about offensive turrets loses(counter for <10 turrets docks will not took so much space, but provide helpful information in combat). Compact logical enemy detector may be helpful too, especially combined with red alert system.
The problem with excluding the core room is that this machine would never work as a template. It's simply too complex. Most people's computers would crash if they tried to 'paste' it in. The only way to make it happen was to make it a blueprint, and as long as there has to be a core room, might as well decorate it, am I right?
