So I had the idea for an awesome mod titled the roller coaster mod. It, obviously, would contain stuff to help out with making railing related builds in the game. For instance, it would include WAY faster powered rails, loop the loop style items, fire hoops, minecarts that look more like actual roller coaster cars, and linking minecarts together to make a train of cars for riders (like at theme parks). But, considering I'm no good at the game, led alone CODING in Minecraft, I can't bring this to life. Before I post this to the ideas forums, I need to know:
1: Is this even a halfway good idea?!
2:Would anyone be willing to help?
3: If this thing did become a project, could I help in any way, even if I'm inexperienced with coding?

Thanks in advance,
