Currently the adjustment for Widen Spell is +3 levels. I have yet to see any character take it. I've yet to see any character published with it, even. It's a killer feat for a high-level battlefield spellcaster with lots of mooks around - think Widened Fireball, Widened Bless, or Widened Wall of Fire - but how many of those are there? For the small-scale mid-level skirmish that is the meat and drink of D&D, it's not so much useless as hopelessly overshadowed.
Even at +2 levels it's a poor choice: compare Widened Color Spray with Fireball. But I think that at +1 level it could be a bit too good, though I'll cite the precedent of Extend Spell.
Would you admit +1 LA if Widen Spell were split into two, with Widen Spell affecting bursts, emanations, and spreads, and a new feat, Lengthen Spell adding 100% to the length of lines and rays?
