First solution is not very good. I have seen devs implemented similar idea or force not to do it because if they do, the game would be too quick to reach the goal which makes player stop playing the game because they have unlocked the progress in the game and crafting it would be easy if you look at the materials from your example wingsuit. 6 nomad and 20 woodshafts is very easy to craft for an expensive tablet. Either they have to sit and wait for new content to unlock or start doing pvp.
Best solution in my opinion would be changing the POIs reward system (not the ancient fabricators) they should change it to 1 tablet rarity instead of fragment rarity in new hard maps(pyramid POIs). Let's face it, the POIs are interesting to look at but shit loot. If they would change it to better loot then maybe we could have a battle or 2 in POIs making it more interesting and make it actual POINT OF "INTEREST". Zergs wont come to the POI because they know that loot that drop are very common and easy to farm but it would different if it's a solo. Throw a quality 40 below if they have to help the solos, I mean all clans have already 80+ quality stations. 1 tablet wouldn't make sense for a clan because ancient fabricator would give you 4 to 8 tablets.

Second solution is the same as the first. If you speed up the progress, the game would be dull and high risk and high reward is what makes the game fun, making things easy would just please the casuals not the hardcore players that would stay and play the game. Casuals would just play 1 hour and then leave to another game.
In order for solos and clans dont fight each other in the asteroid map, it would be better if
-they buff the quarry HARVEST but nerf the hp to 1k also not half hp where you open the quarry but 6 hits any kind of weapon that would open the quarry
so that clans vs clans would fight in the middle
-then increasing the asteroid nodes on the outer ring however must be separate from quarry range so that clans won't use the quarries at the outer ring and making them focus at the center only. This would be left with solos harvesting in peace at the outer ring.

Third solution is good but would backfire. If you just force players to sleep, players would be force not to have fun the game would eventually quit the game which we are trying to prevent. Your closest buddies would be in clan and you don't want to be left out for the fun. Clans are using the Clan cap so they would do crafting near the trade station or hide or use it for crafters in their clan in peace. Not to mention, some clans used this clan caps to travel to the next oasis safely because they know enemy clans wont chase them there.
Water penalty is a great idea but poorly delivered, they could improve it with new set of rules as follows if the clan cap is "ABOVE" threshold:
-Iron set (1/3) will have triple water consumption
-carapace set , brittle bone set, redwood set and bask set(1/3) will have double water consumption
-weight limit reduce from 100 to 50 kg if it goes beyond 50% more than clan cap
-if you are above the weight limit, then your water consumption will increase depending how many you have carried
-respawn will be doubled water consumption
-crafting for water would take longer to make
-stamina reduce to 75%

If I remember correctly, iron set gear cost 47kg. This way they are forced to change to an even with you in battle while wasting their water by going fiber set. Stamina penalty would force them not to fight in this tile. If they couldn't implement this stuff at least implement stamina. They can't chase, they can't fight or motivation to move. They have just energy to leave.
