Well, I don't know how to avoid creating a new structure but you can
use STRUCT_ASSIGN to copy fields from the old structure to the new
one.

IDL> str={a: 3l, b: 'v'}
IDL> str_arr=REPLICATE(str,10)

IDL> str1={a: 3l, b: 'w',c:0l}
IDL> str1_arr= REplicate(str,10)

IDL> struct_assign,temporary(str),str1

where I changed the initialization values so one can verify that the
"relaxed structure assignment" is working.
