Structure block alternative

I saw that Mojang is developing a tool named structure block to save load and create a 3d image of a structure but I think instead of using a block a player should be able to do these activities using inventory when in creative mod.

when in creative mod a new menu should appear named structures from where we can select structures just like we select blocks and structures should be placed just like blocks but

placing should require two right clicks first one creates a translucent version of structure after moving the structure to correct place in place mode another click places the structure.

this menu should only appear in creative mod when a gamerule e.g enable structure menu is enabled .

the structure feature is very near to creative mode and using a block to open menu specify coordinates is difficult it should be as easy as microsoft's 3d builder
