Most Vipassana meditations generally use breathing as well, so it won't be too alien for you, though its practice works just as well -- if not better -- while not seated.
For me, the trouble with breath meditation on its own is that the focus tends to be on using your attention to breathing to relax you, to basically empty your mind of everything except the action of that breathing. This is great for settling your mind, clearing it of unwanted thoughts, and getting you to a peaceful place consciously, and I certainly have no problem with that. However, lucidity depends on your thoughts: dreaming is thought, and anything you can do to elevate thoughts related to your dream, or the actual state of dreaming (as Vipassana does) will be most helpful; pushing those thoughts aside, and getting good at pushing those thoughts aside, might prove a deterrent to successful lucidity.
Also, on a more practical note: breath meditation tends to keep you awake, so it is not the best thing to do, say, during a WILD/DEILD attempt -- I know you don't do this, but thought it worth mentioning.
tl;dr: The experience of Vipassana meditation tends to line up nicely with the experience of LD'ing, while straight breath meditation tends to take a step away from the experience of LD'ing.
