IMHO, Dish Network or Directv shouldn't even bother with HD LIL.
For one, everyone complains when Dish or Directv gives them HD Lite, what do you think they will do with the local signal? I've compaired the PQ of Dish Network LIL (SD) and my OTA DTV stations, my picture quality is so, so, so much better, crisper, cleaner, etc. on my OTA stations. If Dish Network starts doing HD LIL, it will take away from new additional national HD feeds, etc... I'm sorry, I don't agree with Dish Network trying to get locals everywhere--let alone HD LIL, they should have stopped adding LIL stations about 1 1/2 years ago, and started working on their National channel lineup.
Second, especially in my area, I don't really like my LIL lineup, better than nothing, but I want to be able to get the same channels that local cable company gives with their service (I can't get em, I live to far out in the country--by like 1 mile) so I wouldn't like the HD LIL lineup either. I think Dish should work on getting more of the channels that I watch, instead of worring about HD LIL channels. Or, drop LIL all together! Of course, I feel that they should start adding more national HD feeds, but that I know is limited to how much is available.
