a problem concerning the english modal verb might

[wingedfish]

hello, guys, recently i am doing some studies on the english modal verbs. and i encoutered the following sentence, i donot know how to explain, so could you help me out? thanks a lot

Ford urged Morgan to capture these men who, he thought, might be disguised as Quakers.

can i take out the phrase "he thought". this sentence is still correct?

Possible, but temporally ambiguous: if we were to remove the reporting verb (he thought), we would normally adjust the verb form to 'might have been disguised'.

Note also that a comma is required after 'men'.]

thank you first for your answer, but i donot know why my subject is locked.
yes, you have given your answer, but i still have questions for your answer,sometimes, students are not satisfactory with teachers' answers and new questions appear. that happens often.

anyway here is my doubt:
if we adjust the verb form to "might have been disguised", it shows that from the utterer's point of view, it was possible that these men had been disguised. but with any ajustement, can we remove the phrase "he thought"?
i have no idea, can you help me out?
