We already have two Platinum Unbranded Amex and Gold Delta Amex.

​​​​So I was merely thinking of upgrading the Gold to Delta Platinum for the companion certificate and MQMs.

We always finish 5K MQM shy of Silver with the exception of this year where we hit 25K. So figured Platinum Delta will help us always hit Silver Medallion and the Companion certificate is a bonus if we can actually use it.
