So I took some time to think about it and my conclusion is: It's feasible.
Considerations
# My amount of available compute power is fairly limited, as I need to pay bills on my own.
# A "better" frequented production instance of Condor2 server is drawing more CPU time, than I thought it would
The Condor2 server seems to scale not very well with an increasing number of pilots.
But I also run the Condor2 servers in Wine, because Windows is just not an option for me in this scenario.
It could perform better on Windows, but I cannot test that.
I would need to build a new infrastructure to host game services on demand (which costs money to build and operate).
So it's not really possible at the moment.
