If Thomas at John 20:28 was speaking in Aramaic, what are the options for what he originally said?

At John 20:28, Thomas famously exclaims

"My Lord and my God!"

This could be translated in different ways. In particular, ‘Lord’ is ambiguous (Adonai or Adoni?) and ‘God’ is ambiguous (God or god?)

"My LORD (= Adonai in Hebrew) and my God!"

"My Lord (= Adoni in Hebrew) and my God!"

"My Lord and my god!"

In the Greek, it’s

"O Κύριός μου καὶ ὁ Θεός μου"

Assuming Thomas was actually speaking in Aramaic, what are our options for the words and their sense originally spoken?
