I have never used the routine but look at the dbms_metadata procedure GET_DEPENDENT_DDL. It would be fairly simple using SQL to generate a series of dbms_metadata.get_ddl calls where each call generated an index for the table_name used in the driving query against dba_indexes.
We wrote our own index code generator years ago that just reads dba_indexes and dba_ind_columns that works for regular non-partitioned indexes and we have stuck to it. I have written a few scripts that use dbms_metadata but not the all indexes for a table yet.
