On the subject, I think it would be interesting. It'd be a mobile research base, and forward ops base. Give it a less-than-average core, low maneuvering and only minimal fighter cover to make it dangerous only to fighters and bombers. This would require it to be covered by fighters and bombers. Make it so that once it pops, it's popped for a while.
I'm just concerned that if this is implemented we'll see LSF B-ships in New York saying "OH U HAV CARDI EGANBGIN SMUGLER" pew pew pew boom.
