Chrishope,
I reckon the R's assumed that JonBenet would be found by LE or cadaver dogs early that morning. When this never happened JR took the opportunity to immediately relocate BR out of the house. This was patently a revision of any prior planning. The received wisdom for months after JonBenet was found was IDI and LS's psychopathic pedophile with an AE fetish was prime candidate.
If Plan A is to relocate JonBenet away from the house, then cleaning and redressing JonBenet is redundant?
The redressing of JonBenet is intended as domestic staging, not as part of some external crime-scene deposit, but to hide and mask whatever took place that night, since the R's assume that JonBenet's body is going to be discovered by LE, then they go to great lengths to hide her acute sexual assault and over stage her asphyxiation, so to mask any prior injuries to her neck? External crime-scene deposits are rarely staged, commonly the victim is posed.
In short if JR intended to relocate JonBenet then all the redressing is not required, even he would realize once an Autopsy was performed, questions would be asked why the kidnapper redressed JonBenet in clean size-12's, wiped her down with JR's shirt, and fed her pineapple in the breakfast bar prior to whacking her on the head?
I'm not sure what you are asking here, the trial is hypothetical but DocG's theory is allegedly more advanced, it is a theory with lots of evidence to support it, except many aspects are events which were to take place in the future, i.e. not the night JonBenet was killed. This means the theory cannot be tested. JR can never be put on trial using DocG's theory as a prosecution case.

Working from bottom to top;
I don't see that any theory can be "tested" in any meaningful sense. The closest we could come would be a trail.
All theories depend on believing some action is credible or not. All theories require conjecture as to why certain things were done. It really comes down to what each individual "sleuth" finds convincing. W/o a trial to settle the matter, we will forever be going 'round and 'round because we believe different things are likely/unlikely.
The cleaning and redressing wouldn't be redundant in a plan to dump the body. One must consider the very real possibility of the body being discovered under a pile of leaves, in a culvert, at the bottom of a ravine, etc, even if it's days/weeks afterward. Once found, the body should be dressed, if dressed at all, as JBR was dressed at the time she went to bed. (At least in a manner consistent with how the Rs said she was dressed for bed) It would be odd indeed were she dressed in her own clothes, but different clothes than what she wore to bed. At least, it would be odd given the R's story -"we put her to bed, we went to bed ourselves, we woke up to find a RN, yada yada yada."
The redressing can only hide what happened from one of the Rs who is ignorant of the details. With the body in the house, there is no reasonable expectation it won't be found, (that much we seem to agree on) and once found, the coroner will examine it in detail. The SA can't be "hidden" except that the officers on the scene won't know about it, but that really isn't important. The coroner will know, the next day. Likewise, any possible prior neck injury. So all the "staging" you're talking about does nothing at all to hide anything from the authorities, except in a very temporary way. It would hide those details from another family member ignorant of such details.
The size 12s however, don't seem to fit either your theory, or mine. They hide nothing temporarily, as they are obscured by LJs. As soon as the coroner pulls down the LJs, there's a problem. They don't fit my theory either, as she likely was not wearing size 12s at bedtime.
The received wisdom of the lead investigator, ST, was that it was an RDI case.
