Mc Harr asked for a 1500 point list using Dreadknights, Stormravens and a Henchmen unit and at 1500 it's pretty decent though has a single unit which really sticks out (Stormraven + henchmen unit). I rather like the 1500 list even though it is kind of built around this; it just seems fun. You can see all the reasoning here and this is the extension to 2000 points as I didn't want to clutter up his e-mail reply anymore than necessary!
This is more of a fun list than a balanced competitive list as there is minimal fire support and two Stormravens aren't that hard to down at 2000 points, even with Fortitude. At 2500 when you can fit in thirds of things or potentially add Venerable Dreadnoughts it becomes more viable.
To make this list more viable in a competitive sense you could replace the Dreadknights with Psyfledreads for more ranged support but then the Henchmen units are pretty alone up front and as we know, aren't that durable. Anyway consider this posted for completeness sake, fun and discussion.
