I think it's a good idea, but I would have designed it differently. Now it attaches quite a bit in front of the area were the chassis is loaded. Attaching it just in front of the upper A arm would help more. Also, The way it is designed now, there is a long horizontal section which can bend. A tube that attaches just in front of the A arm and goes up towards the fire wall in the straightest possible way (ina more triangulated way) would result in the stiffest construction, I think. A diagonal tube that attaches to the frame rail under/through the upper arm (where the shock bracket is currently located), with an attachment point for the shock would also result in a stiff construction.
