Alpha sheets can now be added to games via the edit option in the alpha sheet display. In addition, statblock embedding should also work for the [sb=show][/sb] tags. Any problems, please post in experimental features with links to the sheet and the game.
Alternatively, I prefer how savage species does it, breaking down all monster HD and LA in one-level packages. Even better would be to make your own monster levels where you spread out the abilities over more HD, but you have no levels without HD, so HD = lvl.
