It feels less problematic than those cases due to those religion's own views on truth and divine prophecy. Christianity largely views Muslim/Mormon views as a kind of Heresy. Toaism/Buddhism don't really map to this kind of thinking IIUC.

I would also counter that a Muslim or Mormon's view of the Bible would probably be very useful, if for no other reason that they would have a alternative but still reverent lens on it; vs an intellectual's which contains little or no reverence. I found a Jew's (Stephen Mitchel's) translation of Jesus's writings to be very enlightening indeed!
