a rough clone of Gun Gale Online. 
In all honesty it sounds fun as fuck. 
VRMMORPG with lasers, swords, and pve, open PVP areas and mobs that increase in difficulty with loot drops and character stats leveling. 
Real money Battle Royal FPS style where you can bring any weapon you have earned, and, while weapons help (and have drawbacks, like weight affecting movement speed), ammo limitations, and other factors, and status may help, ultimately player skill is the great equalizer and lower ranked players still have a shot. 
I think it would do great, honestly.
