    Have you tried loading both CSV files without specifying attribute names? Then you can use the Append and Rename by Example operators to achieve the desired result.

    No problem! I should also mention that if you choose not to treat all of your value as polynominal (e.g text) in Read CSV, instead setting a data type for each column, then you might also consider this alternative solution that uses Transpose and Rename (with dictionary). See below and attached.
