Baznme I agree w much of your theory. People (especially emotionally, psychologically troubled people) operate on more than one level--and there is more than one way in which she could have accomplished the end result of her selfish, idealized life. IMO the passive, subconscious negligence scenario, followed by self-preservation and deception are the most fitting with what we know about her narcissistic, disorganized, ill-disciplined and disordered personality. For starters, for a crime that's premediated there are FAR too many glaring, clumsy, frankly just plain stupid mistakes. (Without realizing, guess this is why my instincts or "mother's intuition" told me otherwise from the beginning.)
For premediation, she sure didn't execute a plan w the slightest coherence nor could she concoct one single story of remote credibility that could possibly hang together--but rather a series of poorly thought, indecisive, spur-of-the-moment compulsive acts, followed by jumbled story after story. All of which have made me, from the beginning, think accident. In many tragic cases but particularly under age four (in a home where there just happens to be a swimming pool), neglect alone--poor parenting and selfish priorities--can EASILY cause a toddler's death. Exact date of chloroform searches yet to be officially released by LE, much speculation, conjecture, and misinformation being passed around. So until we know with certainty, for instance, that the chloroform was used on Caylee (vs trunk) PRIOR to her disappearance, then I'm allowing this may have been part of the cover-up. When the "flurry" of calls are made, she IS at home (prior to which she made only one customary call to be sure GA had left to maintain the lie that she was working, vs stealing, for a living). She was totally obsessed w her new boytoy, a new group of friends etc, so likely went there to use the internet and was too self-absorbed to watch her toddler. Within the HOUR she's trying every person possible, on every phone possible. So what could have happened there at that house, in the short span of 60 minutes? And if she was planning to do something, why in the world choose this location where she might be discovered by someone popping in? To further risk borrowing a shovel from a neighbor is yet another glaring indication this was in no way planned. Why take such a risk when she could have secured one beforehand w/out alerting neighbor. Besides, if you were planning a crime, there would be, all along in the commission of that crime a consciousness of guilt IMO, and you would be aware from that point forth that everything--from web searches and postings on social networking sites, to phone calls and text messages; from store purchases and stolen checks, to traffic and surveillance cams--is traceable and will all lead back to you.
