I do think that what you are saying is more what the rules mean. I think that I will go with some sort of feat, but I can't think of how to make it exactly.
I once made a feat that I really enjoyed but never saw play. It's definitly stronger than the xtra spell feat, and it goes along with other custom abilities I gave to the sorc.
The other custom abilities amounted to basically the ability 1) "Burn" a spell known, ie cast it without paying the spell per day cost, at the cost of no longer knowing that spell. 2) The ability to replace a spell known with another spell known that you either researched or have found in a spell book or whatever. To avoid giving the sorc the versitility of the wizard with this, I gave it an intensive time cost. For a number of days equal to the spell level squared (minimum two days) you have to do a spell setting ritual that takes up the same amount of time as a wizard's spell memorization. So it would take 25 days to get a 5th level spell back (or replaced). I call a spell known a spell matrix, and so laying a new spell known would be laying a new spell matrix.
That gave the sorc's a reason to keep a spellbook, and more reason to research spells.
Then I added two new feats. I reason that you really have to add two feats to be fair to the wizards. They're two similiar feats.
1) Greater Matrix:
You gain the ability to lay an additional numer equal to your charisma modifier of spell levels in (IE, a character with a +4 charisma mod could lay four new first level spell matrices, or two second level, one fourth, a third and a first, a second and two first...)
You can take this feat more than once, it's effects stack.
2) Greater Memorization:
You can memorize an additional number of spells with total spell levels equal to your intelligence modifier. You can still only cast the same number of spells per day. (This feat would give a wizard greater flexibility on which spells he would cast that day). You can take this feat more than once, it's effects stack (can't be taken as a wizard bonus feat).
Combined these two feats do what you want with the sorc, which is give him acess to more spells known, which brings the sorc closer to the wizard class... AND it simultaniously brings the wizards closer to the sorc class by granting them more flexibility in which spells they have memorized that they cast.
