Not sure exactly what that would look like?
As a Jumpship, it would look like a Jumpship - there is desperately little mass left over on a jumper for any kind of mission payload - including payload designed to support assault dropships.
Now, on a warship hull - a warship, with repair facilities, cargo storage, and heavy fighter/small craft bays, intended to serve as a carrier/tender/mothership for a cloud of assault dropships - that could be interesting. It will also be incredibly expensive, but if you only have the ability to build a few warships (limited yardspace for compact core warships) but at the same time have a massive budget, something like Potemkin with some tweaks would probably do the job.
Now that I say it (without looking at Potemkin, Im operating from memory) - what would you change about Potemkin to make her better suited for the task? Maybe a repair bay or two? I guess it depends on whether the mothership is also a combat vessel itself, or a pure tender for the combat dropships. One suggests repair bays and more cargo, one suggests no repair bays, lots of firepower, and still a lot of cargo.
Agility is also an issue - a combat version might need to keep pace with its assault droppers, depending on doctrine. A pure support version could be much slower, and focus more heavily on that support role with the excess tonnage.
As in everything, so much turns on mission and doctrine and budget and shipbuilding capabilities.
