Yeah hehe, <^_^> believe me, I wouldn't have suggested it if you couldn't do it.
2 torps for and aft... I've never done it to be honest; but I don't see any reason it wouldn't work. The only concern I would personally have would be taking down their shields fast enough to start putting those torps on the mark. Given that you'll want the same skills whether you use 6 beams or 4, I'd say just give it a shot, see what you think of it.
