Hyperomelette mark 2
As you'd expect, you'd pick between 4 and 6 or between 5 and 7 letters each turn... the catch is that you must use them all the letters- even if they're not in the same word.
For example, HEZF can become HAZE and OF. Normal stepdown omelette scoring applies (the fewer letters the better) but all letters in the selection MUST be used. The round is automatically forfeited if time runs out and there aren't words using all the letters. Obviously, the minimum number of letters used= 10 points.
Can involve strategy- PVVM can become SEMPERVIVUM in regular omelette, but in hyper omelette can become PERV and VIM or VIVE and MOP.
I can imagine this being a bitch to code but hey, Charlie's always asking for new non-YAKBV ways to play the game, right?
Numbers and conundrum are same as omelette but hyperised, something which is IMHO long overdue anyway.
Secondly...
Funky Numbers
You pick 8 numbers. The three large ones are 15, 20 and 25, and the small ones are 1, 10 and anything inbetween... including fractions, namely eighths and sixths, so a selection could look like '25, 20, 8, 9 1/2, 7 3/4, 3 5/6, 4 2/3, 3 3/8.' Targets can be 100-1999 inclusive, and you may only declare integers (scoring would be as normal). One additional twiddle I thought for this would be to ensure that if you any space that would be filled by a large number in a 3-large pick would be replaced by an integer (like the sample selection with the 8 replacing the 15).
For once, I may actually be onto something here. Needless to say, both of these variants will be included in the pot for the COLIN exhibition game.
