Panel orientation one single MPPT

[Riley]

I understand that it's best to have PV panels with different orientations on separate MPPT controllers. By doing so, each MPPT can optimize for the current conditions and run the panels at their optimum power point.
 
I currently have 4 parallel strings on my roof with the same orientation and want to add more panels. My plan is to add one more string in the same orientation and then one more string with a tilt to the west to pick up later day sun (to help finish off the absorb phase in the fall when I am short on sun hours).

Summary - 5 parallel strings in one orientation and then one more on a tilt so different orientation on the same MPPT.
 
While I know this isn't the best, but given each series panel of a given parallel string has the same orientation, wouldn't this work OK?  I assume that the controller might run the system at less than optimal power point but hoping it would still get a decent amount of power from that 6th string.

Note: I can't really run a separate PV feed to another MPPT controller due to cabling issues from the roof top to my mechanical room.

It should work fine . I have had PV strings at slightly different orientations and some with shading before others. No issues .
