I know this is a little late, but some chapters don’t commonly refer to the Emporer as the Emporer. So role playing as them and using “for the emp” is a tiny bit off. 

for example, the space wolves chapter pack could have come with an added emote for 30-40 dollar bills that added a new emote that said “for the Allfather” in a classic Norwegian accent.  For future DLCs, chapters like the Iron Hands that call the Emporer the Omnissiah can add “for the Omnissiah” or whatever lol I’m not smart on their lore as much.
