The Poulsen system also adds 38 pounds of unsprung weight to each wheel, while providing a 7 hp boost to each wheel. It also doesn't eliminate weight anywhere else. For the purposes of an all-electric wheel-motor car that we've been discussing, it's too low-power.
For the purposes of a hybrid pickup (the OP's question), I'd rather belt an eTek (28 pounds, 8 hp continuous, 15 hp peak for 2 minutes) to the crankshaft and use the mechanical advantage of the transmission to make the electric boost and regen more usable.
A Poulsen on one wheel would be cool for stop-and-go, if it produces enough power (can 7hp direct driven at 1:1 actually accelerate and decelerate the car enough to even keep up with stop-and-go, or do you still have to use the engine?)
