Ask and you shall receive. I made a chart to recap 6-10 cards hands (composition and some possible names), hoping I didn't forget some (that's really possible, if so please let me know). Shall I continue with 11+ cards (as you can't be sure of anything except that some will break the game) ?
For 6-card hands, there are 11 hand types (or 9 if you account 3x2 for both Two 3oaK and Three Pairs), interestingly corresponding to 11 planets in September demo (or 8 planets +Pluto from Solar system), so reverse planets could do the thing.
However, this is hardly generalizable to larger hands (7 cards is 11 hands too if I'm not mistaken, but what would "reverse reverse planets" be? 8 cards is 15/17 hands), and would dilute the planets pool. So a way (I also saw suggested above) would be to compound the base score of a 6-card hand by summing chips x mult of regular poker hands it contains (counting only highest present among XoaK), maybe weighted by numbers greater than 1 if 6-card hands are extremely rare, so they feel rewarding enough. There's no new planets and base scores scale with existing planets even before you "discover" the hand.
6oaK and above would be based of 5oaK, with incremental extra chips x mult, or x1,n mult after cards scoring but before jokers (this incentivizes card enhancements). Same for Straight 6+ and Flush 6+.
For things like Three Pairs, I would sum Two Pairs and 3oaK (it's kinda "Three of a Pair"), but then what about Two 3oaK as it also contains a Full House? Haven't done the maths, but I remember sawing Two 3oaK less often than Three Pairs (which is pretty common), so I think Two 3oaK being more chips x mult feels natural, even if I like Math's idea of them sharing a hand type.
Wild thought as an extra (unrelated to topic and purely theorycrafting): I wonder how far one can generalize the latter to hands with 5 cards or less, so 5oaK, 5oaF and Flush House don't even need a planet anymore. Then what about 3oaK and 4oaK when you push it? 🤔
