Boss death animation in the "boss.mdl" file

Question

is it possible to include the boss death animation into the main "boss.mdl" file?Im asking it because im making some personal mods so i can play with special items and still have some challenge, and that includes bosses as basic enemies, but when i kill sawer or mace (as basic enemies) they just freeze, instead of dying, it's because the developers chosed to make the boss death scene look more cinematic, so the death animations for these guys are separated from the main mdl file.   Soooo, could someone attach these animations so when they die, their death animation starts? (Chainsaw guy aka Sawer and Mace only) thanks!
