Doug Mason: "...for your corrections, advice, and criticisms."
I have no time currently, to think about such esoteric stuff. Most of my spare time goes toward posting material of interest to Asian scholarship* on a FB page, I edit
But I did consider, if I was embarking on such a project, in what unusual area could I look for something interesting about your Thomas? And out of the wilder areas of my mind comes the idea, why India, of course! Because in Indian Christian mythology, St Thomas is considered to be the founder of that church.
Most modern scholarship does not believe that Thomas did found the Indian church, though, of course, it is clear that this particular branch of Christianity is quite old and certainly connected to Syriac Christianity which can be thought of as older than any other branch. Today only a few Christian groups have survived the ravages of time to remind us that once there were more Christians in Asia than anywhere else. While it may not have suited British Christians (of the time of British rule of India) to think that Christianity reached India before it reached Britain, it can only be said that it was possible. Jewish traders were surely trading in India at the time we are thinking about, and the first Christian missionaries (outside of the few mentioned in the NT) usually seemed to travel from Jewish group to Jewish group. So someone got to India in those early formative years.
What use is all that? Only this - that it may be useful to compare the 114 'secret teachings' of Jesus listed in the Gospel of Thomas to ideas that may still be current in the Indian church. Just possibly one could find an overlooked notion that will set the mind on fire (smile) or possibly upset all those smug western Christians who ignore the fact that early Christianity is far more intellectually varied than modern (European) Christians want to admit
* yeah! I know my statement is inconsistent - clearly your topic is Asian in origin and can only be seen through an Asian scholarship lens - but the vast field of Asian studies forces a focus on one section or the other and I choose East Asian studies.

Tharisapalli Copper plate grant (9th century) - One of the reliable documentary evidences of the privileges and influence that Saint Thomas Christians enjoyed in early Malabar.[39] The document contains signatures of the witnesses in Pahlavi, Kufic and Hebrew scripts.[40] It is the oldest documentary evidence available to attest the presence of a Persian Christian community in South India.
And the above copper plates are one reason why few scholars place any value on the Indian Thomas stories, but it does not necessarily mean that the story is a myth.
