I am wondering if some meta magic type feats for hexes would be reasonable.
examples.
Extended Cackle:your cackle hex can have an a greater range of effect
req: witch level 9
Your Cackle Hex is effective out to go feet.
quicken Hex:you have become so skilled with your hexes that you can use them almost instinctivly though with less power
req: witch level 10
up to 3 times per day you may use the agony hex, charm hex, evil eye hex, scar hex, or misfortune hex as a swift action. If a hex is used in this way the save DC is reduced by 5. No other hex modifications may be used in conjunction with this ability.
Hex Reach use your Hexes at a greater range
req: accursed Hex
If a Hex would normally be subject to the benefits of accursed hex you may instead use that hex up to a range of 60 feet. If you use the Hex in this way you may not attempt a second use of that hex if the target resist the hex.
Empower Hex: my taking extra time to concentrate you make your hexes harder to resist
req: hex class
You may use a single hex as a full round action. if you do you may increase the save DC by a number equal to your intelligence bonus (or maybe wisdom bonus?)
Thats all i have off the top of my head.
let me know if you think any of those should be tweaked up or down.
I think the witch class is a fun class but a little limited. these hex feats are intended to make the class more fun to play by adding options but not necessarily power.
you think witches are too powerfull?
I am just starting my witch but planning it out to the higher levels it seems rather limited.
most of their abilities are one shot pass or fail and they pretty much have to stand way closer to the battle than is perfectly healthy.
a dream elf with a monster feat can abuse slumber but I dont think anything else makes them particularly over powered.

Any ole sorcerer or Oracle is a more powerful and better-supported "main caster" than the Witch whose abilities and spell list are redundant ad infinitum.
Witch is a confused mess of poor design and lacking polish -- her power also suffers because of this, don't let anyone tell you otherwise. Behind every Witch-hater you'll find someone who thinks D&D should be played at level 1 with no magic of any kind ever. Oh, and that same person will scream about how weak Fighters and Barbarians are even though they have wildly better one-shot-kill ability than any spellcaster at that level.
I'm afraid, though, that I don't really like the idea of Meta-Hex Feats. The ones you presented don't appear similar at all to Metamagic Feats mechanically because there isn't any opportunity cost associated with using them on Hexes, unlike Spells. Keeping in mind that most Hexes are supposed to scale automatically and indefinitely, and that they don't really have a limit on their uses per day, Hexes definitely don't need Metamagic until after Metamagic Feats themselves are made to not suck.
