Yes, but the shields would be rather situational. Bonewall is good as it will -
-Have amazing numbers as he will eat forever,
-Blocks multiple critters, no matter the attack
However, Jade Shield -
-Protect from Small, 1 hit critters
-Octane. UG.
But On the other hand, Permafrost
-More Defense,
-More Freezed, stopped critters,
-More chance against gods like Minor Phoenix and Osiris
Also, the ulitharid helps against most gods, especially osiris. If you don't want to take ulitharid for any reason, flooding would be nice, however flood requires 3 water quantum per turn. Be aware.
