I like your idea, it's rather good, but it will be hard to get your torps off with both a TL and Marksmanship, it would take 2 turns. I think you're better off going with PtL, which will still allow you to get a focus and your shot off, but in 1 turn instead of two.
I would personally put him with PtL, Advanced torps and Cluster missiles (or just Cluster X2) to get that range 3 shot (Hopefully on a Y-wing or at least an X-wing), Colonel Jendon would be a great help, but not necessary.
What you want to do with him (imo) is to have a few attack 3 ships to make the enemy either pay dearly for attacking him first, or to pay dearly for leaving him alive a while and dealing with the interceptors. You have to just have high threat everywhere...no bunk little tie fighters hardly denting shields.
