One Action Client to Many Action Servers

I would like to know if is it possible to set a single action client to many action servers configuration, such that I can broadcast a specific action type to many servers in the same action namespace.

The number of servers is variable and can grow significantly. So, it is undesired to have one action client for each action server in the client central node.

Each server will accept only related actions via a filter.

So, is there a way to set actionlib to keep controlling actions in such configuration?

Guesstimate answer: Maybe. The major problem will be that action clients manage individual action requests. So, if there are suddenly multiple replies (this includes one accepting an action, but 5 others rejecting), it is probably going to be confused. If you can guarantee that not happening (maybe via a small filter), you can put a broadcast 1:n node in between, where all relevant client topics are relayed to multiple servers. Treat with a lot of care, though!

I've already tried to do that, however I got this message:
