One interesting topic that might be worth discussing is how designing for draft vs. sealed vs. other formats might impact card choices. It's hard enough for me to get more than 4 people together to draft; it's so much easier for me to do sealed round robins or fringe draft variants. I definitely design my cube for sealed, but I haven't noticed any negative impacts while drafting it. Another thing I've been working on recently is building two-color "intro decks" from my cube and using those to help teach some people to play Magic. I need to refine the lists, but so far people seem to like them quite a bit.
Personally, I sometimes am lucky enough to get 8 people together for a draft, which makes it easier for archetypes to come together, but there's enough powerful cards in the cube that even without the full set of cards, people are doing interesting and fun things with their decks. I think including individual cards that lend themselves to being built around works best for smaller groups of people. It can be easy to go overboard with these, as I have done in the past, but testing with cube tutor helps to see how often these sorts of cards appear and how it affects a sealed pool.
I've also done the same sort of deck-building exercise as you from time to time. I usually try to build them 10 at a time to cover each color pair. I've largely used them for testing purposes, to see how the colors work together in order to see how I might further emphasize the synergies I like with more cards, but they also worked quite well as an introduction to what the colors do in the cube. Green paired with Red will play differently than Green paired with White, which is easier to see with decks illustrating the difference.
