No not WP with that bottom side. Will not have the build or movement. She is all cutting bottom side and running top.
If you are looking to get a Reining or cow horse prospect out of this mare you need to pick one. There are a few sires who will sire both but since your mare has a bit if deveristy with the top side which in this case is not bad with the Three Bars. I would pick either a strong reining sire or a strong cow horse sire. Personally with this mare I would go cow horse as that is what she is bottom side and the added speed top side will not hurt.
Also bases on that picture on All breed. I would look for a sire with a much much stronger hip and rear end all the way back. Too sucked up to hold a good stop.
