That is the big error in your thinking. It's not.
Read the Wild Magic ability carefully. It states, that the -3 is only for spellcasting, so it cannot reduce the "base caster level", which also applies to other activities, like item creation.
Both the -3 and the +1d6 are only ever active when you cast a spell. They then change your caster level temporarily, but Practiced Spellcaster does not, it only makes permanent changes (as permanent as it can get in a game, where you can lose a level, anyways), not temporary ones.

The problem with that logic, however, is that it assumes that Practiced Spellcaster makes a change and then goes away, when in fact, I believe its effects are constant.
Consider this possibility, using your logic:
I am a wizard 4/rogue 4. I have an
orange ioun stone which grants me +1 caster level, so my CL is 5.
I learn the Practiced Spellcaster feat. It raises by CL to 8.
By your logic, if I take off the
ioun stone, my CL drops to 7,
even though I have Practiced Spellcaster, and
even though I haven't "maxed out" the feat, and
even though 4 + 4 = 8, because I didn't gain another HD since first learning Practiced Spellcaster.
That just strikes me as silly, from both an in-game and meta-game standpoint. Leaving wild mage aside, I feel it's far more reasonable to assume that Practiced Spellcaster "kicks in" to fill in the caster level gap whenever and whyever one appears, so long as you haven't exceeded the 4 HD cap.
