Can I create a custom Cardtype that acts like a Role?+discussion

I'm thinking of a module that speaks ActivityPub protocols. We might want to try first a mastadon server to server module and a card based client presentation. The bigger prize would be a protocol for economic and other flows. Talking with ValueFlows people. They did VF work with Metacurrency as HoloREA (protocol or tool, not sure exactly).

The interest in this question is around representing and implementing group agency protocols with tracable rules from the indicidual actors (Users or bots sometimes in Decko). No clear routes to funding a project yet, but that needs to develop for this to really move. Just information for now.
