New Nazi Zombie map

I was thinking of a new map for Nazi Zombies, similar to Verruckt, but instead all players are separated into different rooms. There would be different pathways to power room and guns of every country.

First Room:

Russian: Mosin, SVT-40
American: Springfield, M1 Carbine
German: Kar98, Gewehr
Japanese: Arisaka, M1 Garand (there isn't any Japanese semi-auto)

Second Room:

Double-Barrels for all
Russian: PPSH (stick ammo)
American: Thompson
German: MP40
Japanese: Type 100

Third Room:

Trenches for all
Russian: DP-28
American: BAR
German: STG
Japanese: Type 99

After that, Russian/German rooms combine and Japanese/American rooms combine, and at each, there is sawed-off shotgun and one more door to power room.

I designed it like this because it would be an added risk at the beginning, for if you were to go down, you would lose everything.

Other Ideas

Perk Machines:

Quick Revive (Russian spawn room)
Speed Cola (American room)
Juggernaut (German Room)
Double Tap (Japanese Room)
Stopping Power (Russian/German combine Room)
Deep Impact (Japanese/American room)

Deep Impact would be more damage both bullets going through walls and bullets going through multiple zombies one after the other

Other Machines

Betty Dispenser (Generator room) (can hold 2)
Satchel Dispenser (Generator Room) (can hold 2)
Sticky Grenade Dispenser (Generator Room) (can hold 4)

The Dispensers would act just like buying off wall, and you will get 2 more of each every round.
Betties will be RIGHT on D-Pad
Satchels will be UP on D-Pad
Stickies will be DOWN on D-Pad

I havent been able to think of a building to do this in, so can you please tell me and offer feedback on my idea.

Thank you
