I think there should be a feature called "The Undertaker". With this feature,after a player would die and re spawn,they could see the Undertaker to purchase the previous weapons/perks they had the previous life. There is a catch,though. Since Tombstone is not on every map,you have to buy your setup back for 3x as much as you payed for it.
I also have an idea for a perk...
"Engibeer" (intended to sound "engineer")
This allows you to build and add parts faster than usual and allows you to hold more grenades,PaP for less,and re-construct barriers faster.
