I like it.
It is a rather expensive solution, but suitable if a forward base cannot be established in the desired area by ordinary means.
Useful in a system with absolutely no decent hab options.
Also useful perhaps as a central port, orbiting a planet that is snuggled up close to its sun, practically boiling in space.
Even if cheaper hab options are available in the system, maybe the logistical advantage gained by a central port justifies the extra cost of doing it this way.
At this size and cost, I'd be adding bells and whistles for trivial cost and weight--as a final step when designing very large ships or stations, I look at what useful bits I can add for no more than ~1% of the cost and weight of the functional design.
For this behemoth, I'd have 26kt and 34BP to play with.
Obviously the BP is the limiting factor in this case. It would be hard (impossible?) to add 26kt of useful things before spending 34BP.
A refuelling system costs 10.
Another 10 gets you 500kL fuel storage.
And a couple basic 50t scanners perhaps? A thermal costs 5, an active costs 10.
Slap all that on there, and you now have an emergency fuel supply (should something happen to your more significant fuel logistics) and a tiny bit of additional situational awareness.
The tiny extra expense is justifiable, to me, as risk-mitigation. But it's also fun for RP purposes...adds a little verisimilitude to these big beasts.
