Sounds like a cross between longlining and tightlining. You may be onto something. Give it a shot and let us know how it works. Tightlining is usually done from the front of the boat at speeds slow enough to keep the bait in front of the boat. Tightlining is behind the boat at a distance maybe far enough away that the boat does not spook the fish. I don't know if this would matter or not with the method you suggest but the jigs would be close to the boat and just after it passed over the fish. I know hybrids will sometimes hit a lure just a few feet behind the boat in the prop wash so maybe it is not that big of a deal.
