#YES by reducing your caster level and with the Sculpt Spell Metamagic feat but what you can is limited#
(There was no psionic tags when I first answered this questionThere was no psionic tags when I first answered this question as far as I remember)
As both KRyan and Hey I Can Chan pointed out you can indeed reduce your caster level to do so and they also covered the psionic/powers part that was not included in the original question KRyan also included more ways to modify your spell area.also included more ways to modify your spell area.
Another way would be to use the Sculpt Spell Metamagic feat wich states:
(Complete Arcane p.83)
You can modify an area spell by changing the area's shape to either a cylinder (10-foot radius, 30 feet high), a 40-foot cone, four 10-foot cubes, a ball (20-foot-radius spread), or a 120-foot line. The sculpted spell works normally in all respects except for its shape. For example, a lightning bolt whose area is changed to a ball deals the same amount of damage, but affects a 20-foot-radius spread.
A sculpted spell uses a spell slot one level higher than the spell's actual level.
So it is useful to modify the spell area and it could reduce the surface of the spell by increasing it's height instead if you change it to a cylinder for example.
The ''four 10-foot cubes'' is an interesting choice, you can target 4 specific areas (within the spell range limit of course) and they don't need to be adjacent.
It does mention that you modify the area of the spell so a spell without an area of effect cannot be modified by the feat, lightning bolt has an area of a 120ft line (given example) so it can be modified.
Spells with area different from the options of Sculpt spell such as control water could be modified since they have an area but I guess a discussion with the DM would be a good idea.
If the area of the spell has an area of effect dependent on your caster level and you use Sculpt Spell to modify it, I guess the area could increase per level if you find another spell that has an area of the newly modified area spell shape that also goes bigger per caster level , if no such thing exists, perhaps the spell can indeed be shrinked to the proposed area in the feat description (let's say you want to cast Sculpt Control Water to modify the area to 4 10-foot cubes instead will the new shape be bigger depending on your caster level or will it use the fixed size shapes of the sculpt spell feat?), at this point it is out of my expertise, perhaps some help could be provided by the DM if such a situation occurs or someone else on this site.Sculpt Spell has specific boundaries that constrain the spell area
