This is my concept for Bedwars Season 3. Feel free to leave ideas in the comments! 
Theme: 
So, Season 2 happened already, with a magical theming and it’s been really fun. Now, for Season 3 or 4, I have an idea that can be used for the next season: A Space theme 
Maps: 
Planets (Solos) - This map would be interesting, instead of base colours, each base would be a different planet!
Satellite (Duos) - This map is styled like a constelation, with broken objects in space, and a lot of mini constelation islands, like Citadel.
Constellation (Squads) which has different stars as planets and an interesting middle with a giant black hole
Other Less Important Thing: 
You will get a special bed topper or hub title if you max or have maxed Gravity during this period, as it is also space themed, and there could be a new BedWars themed map to connect the two!
OtherOther Less Important Thing: 
Another interesting idea for it would be to remove all gained XP the player gets if they do not get a kill or do damage to an opponent so AFK players or runners cannot get the XP they very much do not deserve.
Level: 
The max level will also increase to 100.
Level Unlocks:

Woah
There will be some new challenges, currencies, a new mode, and new items, so here is what I have:
Items: 
Space Launcher - like a wind charge but more kb and does some damage, but MUCH less then the fireball. (1 amethyst)
Yeeter - replaces the dory, does same kb but gives the player levitation for one second, before stopping. This could mean better clutches, or the enemy taking damage before fighting. (4 emeralds) 
Moon Turret - an upgrade to the turret for 10 diamonds, works like a mini fireball doing 20% of the fireball damage but 2x slower then the regular turret. Cannot break deepslate or higher. (10 diamonds) 
Amethyst Blade - 8 attack dmg
Does +1 more damage every five minutes inactive (not in use) resets when used (5 Amethyst) 
Amethyst Arrow (2 Amethyst for 4 arrows)
Deals 2x damage and a small extra amount of knockback, also sets the opponent on fire for 1 second 
The Levitator - When used, the enemy beside you will levitate for 3 seconds, allowing you to start a combo early. (4 emeralds) 
Space Theif (inspired by an idea by @Blockbyblock98) - This would look like a mini astronaut in your skin, when used it will steal 10 of each generator item from the nearest base, and returns it to you, like an allay (2 amethyst)
Amethyst Armour Trims - When purchased, this would be on any armour you buy, but only for that piece. It wouldn’t do much, until you wear the full set, which will give yoy strength 1! It would cost 2 emeralds per trim piece, and would give an extra reasom to go back to middle! 
New Currency: Amethyst!
Spawns in Moon Craters every two minutes, requires a diamond pickaxe to mine and obtain. Can spawn at base for 3 amethyst, spawns every 30 seconds.
Challenges: 
- To the stars! - Use the Yeeter item 75 times
- Making moons - Upgrade the Turret 50 times
- 3… 2… 1… BLAST OFF! - Use the Space Launcher 100 times
- The rarest - Spend 500 amethyst
- HOUSTON WE NEED WATER - Deal a total of 100 fire damage from amethyst arrows
- Thats enough finals - Final kill 100 players using the Amethyst Blade
(note that the other challenges might reset or increase/decrease. these are just additional challenges)
Daily Challenges: 
Amethyst horder - spend 10 amethyst
Enough yeeting - Use the Yeeter 5 times
BEDWARS LTM: Alien Attack 
2 teams (like mega) - astronauts and aliens
Astronauts get cheaper armour prices and have resistance and weakness.
Aliens get cheaper sword prices and have strength but one hearts less.
STATS FOR THIS MODE WILL CHANGE BUT LEVELS ARE FOR BOTH!
BedWars (ALIEN ATTACK)
Kill - 3XP
Final kill bonus - 10XP
Destroying a bed - 30XP
Win - 50XP
Draw - 25XP
(these may change but these xp gains are just my opinion for now )
if you have any suggestions please let me know and the reason I thought of this just now is because I had this idea before but not as planned out but I just got my account now so yea 
>:)
, I mainly decided to quit because of boredom however. Ideas like this make my day, Ill be somewhat active on the fourms however. Thanks for asking!
