Is it possible to use the netsnmp_serialize_helper_handler after the table_helper_handler?

1) I see that the table_helper_handler is written to handle multiple
requests,
it there any problem injecting the netsnmp_serialize_helper_handler so
it would work after the table_helper_handler finished?
 
2) actually it might work even if the serialize works before the table,
the for loop in the table_helper would just be one iteration, right?
