An observation,
Based on the text above, and on the fact that it was also narrated with descent chains from Ibn `Abbas that "Kursi here means knowledge"
حدثنا أبو كريب وسلـم بن جنادة، قالا: ثنا ابن إدريس، عن مطرف، عن جعفر بن أبـي الـمغيرة، عن سعيد بن جبـير، عن ابن عبـاس: { وَسِعَ كُرْسِيُّهُ } قال: كرسيه: علـمه.
حدثنـي يعقوب بن إبراهيـم، قال: ثنا هشيـم، قال: أخبرنا مطرِّف، عن جعفر بن أبـي الـمغيرة، عن سعيد بن جبـير، عن ابن عبـاس، مثله، وزاد فـيه: ألا ترى إلـى قوله: { وَلاَ يَؤُودُهُ حِفْظُهُمَا }؟
Also as is apparent from the verse itself linguistically (review Tabari's explanation) it's possible to deduce that what Ibn `Abbas was doing is to explain what a Kursi is according to Arabs as is the habit of all exegisists/Mufassirin.
So he had two reports, when asked what a Kursi is, he explained it as a stool used by kings (to rest their feet or whatnot) then when explaining the verse itself he said it means knowledge in this context.

Well, i am very glad one members has chose to directly engage in dialogue. If the length of my posts is what puts you off brother Hani, i will try to work on that specifically for your sake, as you seem willing to at least engage in dialogue.
Let me address your response:
Your response would be adequate for Ashari and Maturidi scholars who tend to favour this sort of interpretation. However, what can we say about the Salafi-Athari? From what i gather, the majority of Salafi-Athari scholars believe that Allah , the Almighty, literally has two feet, but how it is not known. From my research i have also understood that the Kursiy is considered a creation of Allah, and the two feet part of the attributes of Allah. Is it a coincidence that the 'two feet' which are widely accepted by the Salafi-Atharis to be literal parts of the Almighty, happen to be over what is known as the 'footstool' ? You have given one interpretation i do not think will be accepted by the vast majority of the Salafi-Athari scholars.
If we refer to this:Abu Moosa al-Ash‘ari (may Allah be pleased with him) said: The Kursiy is the place for the two feet,
and it creaks as a saddle creaks.
Narrated by ‘Abdullah ibn al-Imam Ahmad in as-Sunnah; Ibn Abu Shaybah in al-‘Arsh, 60; and by Ibn Jareer, al-Bayhaqi and others. Its isnaad was classed as saheeh in al-Fath, 8/47 and by al-Albaani in Mukhtasar al-‘Uluw, p. 123-124
It just pushes away the idea one can interpret traditions like this in a metaphorical manner. Furthermore, the Shaykh who wrote this article:
https://islamqa.info/en/166843 first affirms Allah has two feet, and that the two feet are literally above the foot-stool and this is the place of the two feet. There is no attempt at describing the Kursiy as knowledge.
In fact, Ibn Uthaymeen comments:
There are those who say that the Kursiy is the Throne because of the hadeeth, “Allaah will set up His Kursiy on the Day of Resurrection.” They think that the Kursiy is the Throne.
Similarly, some people claim that the Kursiy is Allaah’s knowledge, and say that the aayah (interpretation of the meaning)“His Kursiy extends over the heavens and the earth” [al-Baqarah 2:255] refers to His Knowledge.
The correct view is that the Kursiy is a footstool, and the Throne is that which the Most Merciful rose above (istiwaa’). And knowledge is the attribute of the knowledgeable one by means of which he understands that which he knows.
(al-Qawl al-Mufeed Sharh Kitaab al-Tawheed, 3/393, 394).
I therefore do not think your opinion will hold with the vast majority of the Salafi-Athari scholars and even some among the Ashari and Maturidi. Either-way, your attempt showed some skill and intelligence, and i have to commend you for that, but unfortunately it is not an adequate response, but a good attempt.
