I would start with a 'stronger' number of bass than what is often suggested for a northern BG-LMB pond. Normally this is 100 LMB/ac and you have close to an acre. Your goal is extra heavy predation of YOY carp (young of year). I think somewhere around 140-175 LMB or even 200. This number of LMB will also strongly limit PS recruitment, thus you may have to add BG or HBG to have a successful panfish fishery. However the panfish that survive in your pond will be big ones. Maybe some LMB of each size 3-5" and some 6"-8". I think the larger LMB will eat some of the YOY carp escapees as they grow to 2.5". Although if some of your PS will be 1.5" then stay more with the 3"-5" LMB. If you decide you have too many bass, IMO it will be easier to remove bass than carp.
The other thing that I would try and do is minimize the amount of spawning habitat for the carp. Research carp spawning habits. As I know it carp like to spawn in shallow grass areas around emergent vegetation. Koi raisers use cotton strand mop heads as spawn substrate for their koi. So this type of structure you want to minimize. Given the chance carp will find a way to spawn on just about any shallow structure. They wallow around shallow shoreline areas when spawning. At the lake we used to get carp eggs attached to the bottom and sides of our 20ft walleye fishing boat that was morred in the marina.
Another thing you should investigate is the use of a flag net or a large mesh gill net that will only catch big fish based on the size of the mesh. This net is designed to catch - entangle large fish and should select for adult carp. Small fish will swim through the large net mesh. Another option that I would seriously explore is to use a cove or corner of the pond and during summer of pre and post spawn bait it with soaked corn. Carp can be trained to regularly feed actively in this area. They will learn to depend on it. Once trained and a short while after the daily corn feeding has been distributed pull the flag or gill net in behind the carp feeding area to entrap and catch them with the net. Continue to regularly feed and use the net only once every week or two and you should catch lots of adult carp during the course of a summer.

Also check with Memphis Net and Twine for nets.
If you need advice of how big of a net mesh call the company; they are specialists. Tell them what you are doing and it is for catching adult carp. They will advise you which type of net is best.
Website Quote ""Flag Gill Nets aka Shirt tail nets. Flag nets are the least expensive of the gill nets, but when used in still water and little or no wind, they are still quite effective in catching fish. Flag nets are constructed out of multifilament or monofilament gill netting with a small rope at the top. There are no floats, leads or bottom rope. The net is fished by tying it between trees, stakes, or jugs. As the fish approaches the net, the water displaced by the fish's movement causes the netting to swirl, catching the fish through gilling or tangling. Flag nets are not recommended in moving water or in windy conditions.""
