WX surrounding the msp airport caused ATC to formulate plan to route all traffic over one arrival route. However, approach control changed runways causing the plan to cause traffic delays due to volume, WX and rough ride due to turbulence.

Narrative:
WX was impacting the arrival routes into msp. A plan was formulated to take all the msp arrs over the GEP3 arrival. When a majority of the airplanes were in the sector or on the boundaries, msp approach called for a change in runways, creating delays in excess of 10 mins for the first arrs. Due to volume, WX, and ride conditions this made for a very unsafe condition.
