1. New reviving feature, something like AAPG. it can be basic and doesn't need to be fancy stuff.
Possible, may take a while to get working right.
2. New custom weapons added? Also including knife?
Possible but highly unlikely unless it's from 2.8.5 or a copy-paste of another weapon. This takes animators and extensive 3D work, both of which we can't rely solely on ELiZ for, it would take up far too much of his precious time.
3. Objectives re-thinked and re added in making better teamwork. In hospital 2 objectives etc, 1 team to rescue VIP and other to get a briefcase. for doing 1 objective you get less points that for doing both of them.
I want this, I really do. I would like to see my Battlefield-style objectives implemented in other maps. There was an issue however; the objective can only be taken by one person at a time. Someone else on your team can come in and prevent both of you from taking the objective. I recall that ELiZ looked into it and would have to make a sub-class objective actor with a couple variables changed. I don't know how much work that would take but again, ELiZ's plate is pretty full.
4. Improved sound, lessen the sound if possible in any way so people don't hear you across the map.
I'd like this too but it's not going to happen. We don't have the engine source and even if we did, we don't have coders knowledgeable enough in engine design to modify these kinds of things.
5. Adding female character soldier.
6. Possibility of perks?
8. Adding custom in creating your own soldier or soldiers face?
As shown in your videos below, I 100% agree. Would love to see these.
7. Adding flag/bomb objective feature?
That's pretty much what Mout McKenna is. I've often thought of more capture-the-flag maps. They would be fun, especially if the Battlefield-style objectives could be done. Multiple flags being taken in a radius. Theorhetically, we could do random spawns for players and objectives to really mix things up.
9. Work on crusade mods to bring back fun servers fully tracked?
Some of the mods could be implemented but they would have to be broken down and separated. We'll never fully track the Ultimate mod, there's far too much stat abuse and unrealistic gameplay with it. Some aspects though, are nice and can be tracked. 82nd Shad has rebuilt and improved the WeaponPicker mod. He may be interested in reworking some other mods to get them tracked or re-released.
10. Swap teams after 6 rounds depends what is the total amount of rounds like in aapg.
I see no reason why this couldn't be added, set as a server-side option for admins to enable.
11. Editing main maps with holidays, like july 4th maybe adding american flags or such at these kind of events.
This one is just a matter of time. Me & Killaman hardly have any time to edit maps as it is, we should focus on adding slots to existing maps, fixing things up and stuff like that. Holiday maps are fun but they're short-lived and take a decent amount of work.
12. Adding traps, mines, wired trap? 
Could you elaborate?
13. Adding voice sync like in aapg, using ts3 really lags for me and it would be really helpful to communicate with others.
I doubt you'll get this. People will still prefer TS3 and it would take a massive amount of work to get VoIP in-game and working properly. Not really worth the time investment.
This is something that eliz has worked on
Female character =
^^ If we can get that, it would be sweet. I don't know about using the skins/attachments as perks but character customization could be fun. I suspect other things like headphones, turban, the PWNED target and others could be attached to a player with more work. Anything to increase the fun factor.
