Imperial Guard 6ed Ally ideas

I should be able to play my army list with the following allies:

Dark Angels:
HQ Librarian

Troops Deathwing Termintors

Heavy Land Raider

or

Blood Angels:
HQ Chaplain

Elite 3x Priests with Melta Pistols

Troop 10 Jump Pack Marines with 2 melta and a power fist

This would give all of my guardsmen FnP and a fearless scoring jump unit with a powerfist.

Aren't they nerfing FnP to 5+?
Probably for this very reason. Still it's a nice combo.
