Increased Size of Structure Block

In Minecraft the Structure block allows you to save and load structures on Bedrock and Java edition of the game. The structure block is so amazing but is missing the functionality of creating giant structure like ships. Currently you can only go 48x48x48 In Java Edition and 64x256x64 In Bedrock Edition. But what if increasing the size to at least ~300 to ~400 to even ~1000 for X, Y, and Z Axis so you can build bigger structures and save them. Like if you wanted to build a giant Cargo Ship you could instantly use a Structure Block and save the ship so you can always load it into another world or never loose it. So my suggestion is to increase how big the structure block can do to at least ~400 but it would be nice to be able to save up to ~1000 on the X, Y, and Z.
