o.k. now i see the whole fellowship, i have some suggestions:
first, why not using Steward of Gondor? its not less thematic, than eagles at helms deep (would put it on eowyn)
then i would put the red cards all to the gimli-deck, it makes it easier
basicially the elfhelmdeck will defend and the gimlideck will strike, so more ranged should be done because there is no sentinel.
it is not effective to play "a litle bit" of eagles. full or not (beside perhaps the cheap for chump etc.)
so, my version, keeping these heroes would be:
elfhelm, out:
all tacticcards (keep song of battle, its good for eowyn and for elfhelmbonus) = 6 cards

result 14 cards you can take:
gimlideck:
out:
result out: 23 cards
in:
2 Northern Tracker (if playing the steward on Éowyn you can play them easily
3 Rohan Warhorse
3 Tireless Thoroughbred this is THIS horse for Gimli
1 Vigilant Guard THIS non restricted attachment for Gimli
1-3 Thorongil great on gimli or legolas, specially with a horse+elfhelm, i would take 3 but i am addicted to this card
3 Foe-hammer
3 Dagger of Westernesse
if you have more than 3 add additional Westfold Horse-breeder
+1 Feint (nearly best tacticcard in the game)
fill the remaining slots with good allies:
if you (whyever... ;) ) want to remain on your half-eagle-half-inefficient way, replace at least the Lórien Guide with Northern Tracker and discard the Watcher of the Bruinen and add 3rd The Eagles Are Coming! and 3rd Feint try to include Foe-hammer and Tireless Thoroughbred and/or Vigilant Guard for gimli.
hope you appriciate my advice, happy questing
