Most of what you ask for is already written, is simply a configuration change.
Things that would be very difficult are.
1. Pick where you dual/match.
2. Adding fields , other then for landing and exiting. Completely conflicts with your other goals.
3. Making all sides the same team makes match with 2 v 2 4 v 4 ext, very difficult. But we can already set kill shooter on a per match queue type.
Settings the are avalible on a per queue setting.
"Queue Enabled",
"ELO Scoring Enabled",
"Touch ground death",
"Death Match",
"Auto Launch Match",
"Launch All In Queue",
"Spawn In Circle",
"War Cash Awarded",
"Spawn Users Country",
"Easy Mode Only",
"Real Mode Only",
"Lead Sight Enabled",
"Kill Shooter Disable",
"Ai Enabled",
"Kill Race",
"Auto Repeat",
"Can Join In Progress",
"Free For All",
"Balance Sides",
"Drones Score ELO",
"Disable Blackouts",
4. Stating rules would be a disaster and just create headaches.
Match play is already completely free.
