How to handle file inputs with changing schemas in Talend

Questions: How do I continue to process files that differ substantially from a base schema and that trigger tSchemaComplianceCheck errors? Background Suppose I have a folder with Customer xls files called file1,file2. file1000 . Assume I have imported the file schema into Talend repository and called it 6Columns and I have the talend job configured to iterate through each of the files and process them

1-tFileInput ->2-tSchemaCompliance-6Columns -> 3-tMap ->4-FurtherProcessing 

1. Read each excel file
2. Compare it to the schema 6Columns
3. Format the output (rename columns)
4. Take the collection of Customer data and process it more

While processing I notice that the schema compliance is generating errors ( errorCode 16 ) which points to a number of files (200) with a different schema 13Columns but there isn't a way to identify the files in advance to filter then into a subjob

How do I amend my processing to correctly integrate the files with 13Columns schema into the process (whats the recommended way of handling) and designing incase other schema changes occur

1-tFileInput ->2-tSchemaCompliance-6Columns -> 3-tMap ->4-FurtherProcessing | |Reject Flow (ErrorCode 16) |Schema-13Columns | |-> ?? 

Current Thinking When ErrorCode 16 detected

Option 1 Parallel. Take the file path for the current file and process it against 13Columns using a new FileInput before merging the 2 flows back into 1

Option 2 Serial. Collect the list of files that triggered the error and process them after I've finished with the compliance files?
