3 of my ideas for community projects in 1.16 + reply your ideas!

Hello there,

          Recently, anticipating the resets for 1.16 being the first time I'm going to experience a full reset, the same for many people, I have been brainstorming ideas for the community to work together on, such as projects, railways and transportation across the server altogether. Many of these I just thought would be cool to share, and thought that some people would like to add onto or even add their ideas onto for other members of the community to see. 
          I'd like to, before I begin, thank you for taking interest in this post that I've made, and tell you that you can feel free to comment your ideas too.

Idea 1:
          My first idea is one to build a "mega-structure" at the End, maybe like some arena of sorts, where we could use the end's natural shape and the positioning of the Obsidian Pillars in the End to make an interesting and unique structure as a community, which can represent all of us and our contributions to the server as a community.
          This idea is mostly inspired by a video which a very good builder made on YouTube, which can be found here.

Idea 2:
         My next idea is to build a railway / underground railway across the server as a huge community project to link the community together and make it easier to travel between certain places (such as towns and bases of which players might want to share more easily with others.) This'd bring the community closer together - probably quite literally - and encourage people to expand further with their ideas, bases and builds. This'd take time, however, I'd be sure this project would be worth it in the end.
         
Idea 3:
           Players should for sure be allowed to help in the creation of the new shops warp, spawn and other areas for 1.16. This one I've already mentioned before a few times as a cool idea, but I'd like to mention it here too as it'd make a cool community project. Similarly to idea 1, this'd represent the community working together for a long time (until the next reset) and would allow for everyone to meet up with each other again after the period of long inactivity in Oasis whilst awaiting the reset. It'd give the player base something to do whilst in quarantine and could even speed up the process of the construction of spawn. Whilst this has many risks, it should be safe to do as the community is so close together and it can be easily managed if done properly.

Thank you.

TL;DR: My ideas are that it'd be cool if the community build a huge structure in the end, a railway to connect towns and bases as well as the community being allowed to help build spawn, /warp shop and the such.
