I'm sure you must realize that
name2 = { file, name:' ', header_size:0, data_type:0, format:0, $
dim:[10,20,0], key:' ' }
is perfectly legal.
If you want the size of the dim array to be variable, then simply use unnamed
structures rather than named ones, e.g.
unnamed = { name:' ', header_size:0, data_type:0, format:0, $
dim:[10,20], key:' ' }
