Restrictions of different MIMO config per sectors of same site

Hi Experts.

Is there any drawbacks from setting a 3 sectors site as per below
1rst sector:2x2
2nd sector:2x2
3rd sector:4x4

Are there any drawbacks or restrictions?

No, i believe.

I don’t consider any drawbacks, we have been doing such optimization to increase TDD coverage where FDD-TDD overlap to be increased.

You may face some conditionally if sector separation is less than 50 degrees.
