First of all I advise you to install the 'Star Wars Mod',
made by me (Seneca) and FluF5y.
This mod changes the weapon sounds into Star Wars blaster sounds
and the in-game and menu music into Star Wars music.
(And I changed a few textures)

Download the Star Wars mod here:
http://www.moddb.com/mods/blockstorm-star-wars/downloads/blockstorm-star-wars-10
This download contains a readme with the necessary information, but I can't stress enough to make a backup of your original files.

This mod isn't finished yet, but the current state is enough to provide you with a great Star Wars atmosphere.

An impression of the mod (without in-game music):
This is however representing an old version, the mod has been updated after this video

This the ultimate Star Wars workshop collection, containing all notable Star Wars workshop items:
https://steamhost.cn/steamcommunity_com/workshop/filedetails/?id=402596390

Because of the large number of Star Wars workshop items I made a few sub-collections:
https://steamhost.cn/steamcommunity_com/sharedfiles/filedetails/?id=444559296
https://steamhost.cn/steamcommunity_com/sharedfiles/filedetails/?id=585343395
https://steamhost.cn/steamcommunity_com/sharedfiles/filedetails/?id=586064430
https://steamhost.cn/steamcommunity_com/sharedfiles/filedetails/?id=586077978
https://steamhost.cn/steamcommunity_com/sharedfiles/filedetails/?id=673437420

These sub-collections are the different factions of the Star Wars universe and contain all sorts of infantry, mechas and main characters of the movies.
You can also find weapons that fit with these specific factions.

If you're not nerdy enough for this sh!t, but you still want to join a Star Wars event or play with your nerdy friends, these are 4 basic character skins you can use:

Clones vs Droids
If you're blue:
Clone Trooper
If you're red:
Battle Droid

Rebels vs Stormtroopers
If you're blue:
Rebel Trooper
If you're red:
Storm Trooper

Just a heads up, if a skin has already been linked, I won't link it again just so that this doesn't become too long of a section.
