One of the things to come out of Artemis 1 was that NASA’s Deep Space Network was very overworked supporting Orion and eight cubesats + normal operations and maintenance. This led to some slightly heated discussions of solutions. Now there's a reasonable amount out there about ground based optical solutions, but I wasn't able to find good resources on size of relay satellite optical payloads.

Now SpaceX are investigating using Starlink as relay satellites already, but it's unclear whether this is restricted to other objects in LEO or LEO adjacent orbits. (Polaris Dawn will demonstrate this service). There is a fairly drastic distance change from LEO relay to Cislunar relay, so presumably the complexity increases by a bit as well. So what I want to know is the size of the optical packages required for this to understand whether they could fit on a Starlink scale platform.
