950 BCE is a ridiculous date for the writing of the Pentateuch.
Richard_Elliot_Friedman made a similar suggestion in Who Wrote the Bible?

He also made the absurd argument that the Jahwist was a girl.
That was all over a quarter century ago and I didn't think anyone took that seriously anymore. There is doubt that Hebrew even existed as a language in the 10th century
For example -

The good news is that it's from the 10th century and professor Galil's interpretation is that the shard has Hebrew writing reminiscent of something in the bible.
Khirbet_Qeiyafa, the bad news is that he is wrong.
http://www.rollstonepigraphy.com/?s=Khirbet+Qeiyafa is a more sober appraisal -
The Qeiyafa Ostracaon is an important inscription from the late stage of Early Alphabetic. Regarding its language, some have argued that it is written in Hebrew. This article, however, contends that there are no discernable diagnostic features in the ostracon that mandate such a conclusion. Furthermore, the article also emphasizes that the script of this inscription is certainly not Old Hebrew, nor is it the immediate precursor of the Old Hebrew script. Rather the Old Hebrew script derived from Phoenician. Thus, there is some distance between the script of this inscription and the Old Hebrew script. Finally, the article contends that it would be difficult (because of the dearth of
data) for grand proposals about statecraft and literacy to be made on the sole basis of this ostracon.
Galil, other than just offering a dubious translation, makes erroneous claims about what are Hebrew versus Canaanite words. The link refutes these claims.
The problem seems to be that if the Pentateuch was written by 950 BCE, what language was it written in? Not to mention, what was it written on?
Your comment about the Jahwist being earlier than the priest has merit. I recently also had this impression. However, I was surprised to learn that it is questionable.

Consider the Tower of Babel - Genesis 11:1-9
Everyone on earth had the same language and the same words. 2 And as they migrated from the east, they came upon a valley in the land of Shinar and settled there. 3 They said to one another, "Come, let us make bricks and burn them hard." -- Brick served them as stone, and bitumen served them as mortar. -- 4 And they said, "Come, let us build us a city, and a tower with its top in the sky, to make a name for ourselves; else we shall be scattered all over the world." 5 The LORD came down to look at the city and tower that man had built, 6 and the LORD said, "If, as one people with one language for all, this is how they have begun to act, then nothing that they may propose to do will be out of their reach. 7 Let us, then, go down and confound their speech there, so that they shall not understand one another's speech." 8 Thus the LORD scattered them from there over the face of the whole earth; and they stopped building the city. 9 That is why it was called Babel, because there the LORD confounded the speech of the whole earth; and from there the LORD scattered them over the face of the whole earth. (Gen 11:1 TNK)
Babel, of course, is Babylon and this passage recalls Jeremiah 51. An interesting question is which one is written first... personally, I don't think one can intelligently place one almost 500 years before the other.
Of course, your claim that there was actually a United Kingdom is almost outrageous in this day and age. However your situating Solomon's wives and concubines in his stables makes up for some of the probable factual inaccuracies with humor.
