Please look at the following sentence------To answer this question, first, it is evident that the wh-sluice
in both CM and NCM sluicing must be contained within a CP structure,
even though their internal configurations may be different It appears to me there is something wrong in the underlined part of the sentence. Cant tell what exactly it is. Could anyone tell me what (if there is  anything) is wrong with the sentence.

Nothing seems anomalous about that underlined part to me. Maybe you'd prefer a singular "their internal configuration" -- in a distributive rather than collective sense?

Thank you , Now I found out the problem with me. Checking the corpus of my own write-ups , I observe that I have never used 'even though' with 'may be' , This I presume was because my  subconscious  mind has some how formed a rule that 'even though ' is incompatible with 'may be' .   ( may be due to the influence of my first language) .

No problem with that. In fact it is a common rhetorical device. "Even though that may be correct, I still don't like it." etc. It's like the archaic "Notwithstanding", where you are actually asserting something despite the possibility modal. Or it can be literal possibility. Depends on context. In the case of the quoted sentence above I read it literally, as possibility, not conclusion.
