I have an idea for a mod which i think would be really cool.
My idea is to have an extended crafting table which you could make more items on.
For example you could make a 4x4 crafting table instead of 3x3. (or maybe even a 5x5 table)
I don't have a crafting recipe for the table, make it what you want.
Maybe it could be like a double chest and you put two crafting tables together, maybe you would put some crafting tables together in your crafting grid, i just don't know.
Some 5x5 recipes could be like:
Could be like a huge sword to own things with.
You could replace the Iron with diamond or something too.
This could be like a super pickaxe or something.
Other than that, it's up to you if you want to make this mod.
