Possible (yet fairly unlikely) fix to war inconvenience

So in my clan, many people complain about war being a serious inconvenience. They dont like breaking from their farming or pushing to build a different army for war. They also complain about the costs of these armies. I myself face the issue. Im pushing im champ (around 3500 now) and when im not on shield i wanna be raiding non stop, and when on shield i like to go and actually live life haha. But back to the war topic....
What i propose is a way for players to cook troop builds specific for clan war and seperate from your base. Something such as a menu where i can choose what spells and what troops i want to bring into my war battle. Now that we have war specific bases seperate from your main village, im hoping we can get a war specific army thats seperate from your regular army. This would also fix the issue of people sitting out of war because they have upgrading heroes. Many people dont get to participate in war because they wanna improve their heroes and such. Anyways.... Please leave any ideas and opinions below, id love to hear them :)

I was suggesting to increase the war bonus, but if not, this idea would be ok for me, as long as wars became less costly in time and resources. :)
