Survival Mode Level Suggestions :)

I know you guys got your hands full with a bunch of requests already, but figured I'd post this to see if anyone else agrees with these 7 level suggestions, as I think it'd be pretty sweet to eventually include and play these levels in Survival Mode.
in no particular order of what I'd like to see most, rather just campaign order...
- Church (Mission 2, Part 4)
- Assault (Mission 3, Part 4)
- Trainyard (Mission 4, Part 3)
- X-Labs (Mission 5, Part 2)
- Dam (Mission 6, Part 1)
- Village 2 (Mission 6, Part 2)
- Chateau (Mission 6, Part 3)

If I had to pick a top 3, it'd be:
1. X-Labs
2. Assault
3. Damn

I think if all the x labs and church doors would be unlocked (and tweaked a bit) , it will be a whole arena like experience, thus perfect for survival
