First off, I view Sculpt Spell as a little broken as is.
In my game, you cannot cast it on an area spell that has a lesser area then what Sculpt Spell grants. In other words, you cannot use it as a cheap way to Widen Spell a spell.
How do you work that? Do you count up how many squares the spell would have covered in it's original form and then ban the application of sculpt spell on any spell that has less than sculpt spell's area? Which version of sculpt? Or do you do it for a specific shape of sculpt when that shape is applied to a spell? Does the spell not work, or is it reduced? etc etc.
Secondly, the feat does not state that you can change the shape on the fly. Making "on the fly" changes is beyond the scope of what a +1 metamagic feat should do. That would be like putting Silent Spell and Still Spell and Eschew Materials into one +1 feat and then choosing the component you want to drop at the time of casting.
Yes, yes it would. Except that any of those three (excluding eschew, which is a freebie and not metamagic at all) are significantly more powerful than changing the shape of a spell, especially in a case-by-case basis, and with the additional restrictions you place on shape spell. You'd have to evaluate this new feat based on it's power.
Saying that some hypothetical feat with totally different uses is powerful, and therefore this feat is too powerful despite being only trivially similar is a bit of a crap argument. Wish is a spell. It's too powerful for a 1st level game. Dancing lights is also a spell. Clearly it's out of whack for a 1st level game.
Finally, I do not like the "4 cubes" option because it does not state how you can arrange the cubes (e.g. whether they have to touch on a side, a corner, or not at all, etc.). Plus, depending on arrangement, that can make an area effect spell nearly individual target level of targeting which virtually no other area effect spell has.
Like any other spell which has an area of "X 10ft cubes", or a notation of (S) for shapeable. The cubes have to be touching, and no feature of the area can be less than 10feet. That's a far cry from 'individual targeting'
I also think that the "metamagic range" counter argument is not very strong. Most spells allow for a range "up to x" and Enlarge spell increase the maximum range. That does not change the "up to x" portion of a range spell. The range variability is in the spell before applying the metamagic feat. That's an apples and oranges type of argument.
I'd disagree with that - the feat changes the range of the spell, not the maximum range. Certainly, almost any spell (except for a spherical burst or spread) determines it's actual shape at casting time (different directions for most of them, different arrangements for 10' cubes). It's just that usually the shape taken must be a certain class of shape.
Similarly, a spell which has two different forms need not have the form chosen at memorisation - a prime example is telekinesis. It has no text to suggest that the selection of form is performed explicitly at casting time, but I'm fairly certain that it works that way - I've yet to see any character anywhere ever written up with "telekinesis(violent thrust version)" on their list of memorized spells.
