Hoop Thrower

The only component I've thought of right now is possibly a Field Hospital UI. I'm not sure when it would be unlocked, but it would provide food and science (and health with CID) and heal friendly units ending their turn on it. It could also be built in city states where it would provide influence for you every turn that it's being worked.
Could the Hospital heal any unit instead? But if it heals an unit that is not yours it excerts influence over the unit's owner.
