I still wonder how well the Lanc will really fair in an MA environment. Look at the new B26; it's faster than the Lanc, and still it is being brought down in numbers. The Lanc has a similar ceiling, is a bit slower, bound to be less maneuverable, and also lacks a belly turret.
I'm not saying that I wouldn't want to see one, but it will suffer heavily from fighter attention. A Mosquito is a far better option as a Brit bomber IMHO...
