Does anyone see any issues with this itinerary for Mini RTW?

EWR - NRT (Open Jaw)
CTS - ICN (Stop)
ICN - TPE (Destination)
TPE - JFK (Return)

MPM for EWR-TPE is 10,959 according to Aeroplan site (using this method).
GCMapper distance for EWR-NRT-CTS-ICN-TPE is 9025, well under the MPM.

Does this work? Thanks!
