Try this, which is what I am using:
Code:
                recruit_pool "NE Late Bodyguard"  0.6   0.2   1  0  requires factions { england, scotland, france, hre, denmark, poland, hungary, }
                recruit_pool "EE Late Bodyguard"  0.6   0.2   1  0  requires factions { russia, }
                recruit_pool "SE Late Bodyguard"  0.6   0.2   1  0  requires factions { spain, portugal, milan, venice, papal_states, sicily, }
                recruit_pool "Greek Bodyguard"  0.5   0.25   1  0  requires factions { byzantium, }
                recruit_pool "ME Late Bodyguard"  0.6   0.2   1  0  requires factions { moors, egypt, turks, }
If you only want the early BGs, remove the "Late" from the respective code
