I too once sought to have a collection of EDH decks in all 32 color combinations but soon ran out of inspiring ideas as to what to build. I find that more than color combinations, it is unique card choices, strategies and deck mechanics that are engaging. Once I built an EDH deck around a certain theme or mechanic I simply can't be bothered to repeat those in another deck. My goal is that in each of my decks, the ~10 most exciting cards for that deck are also unique to that deck, or at least fulfill a different function.
Kind of where I am now, I can only have so many decks that have the same win con before it gets boring.
Good/current example is my Chainer, Dementia Master and Meren of Clan Nel Toth decks. While both decks are different there is a lot of similarities in how they win and play.
If the goal is to have unique decks for each color combination, then you really need to be careful about which graveyard decks you run. Chainer and Meren can play quite differently though... Chainer can focus on reanimating big things, while Meren plays more like Karador most of the time.
My issue with getting to the 32 different colour combinations is that sometimes I like multiple commanders that overlap in colours. I now have two BR decks, two Karador decks (one is optimized, one is Spirit tribal).. and I am working on two BG decks.
Also, life is getting busy. I used to build 3-4 decks per year, now I think I will try to get one done per year, and focus on updating my decks.

Do you have multiple copies of expensive staples or do you use another method like proxy or swapping cards between decks?
