My reading of the rules, as found in the preface to the former PTS, now ACS, is ‘no’. This preface says the examiner is to choose ‘3 different types of approaches’, then lists the acceptable ones. The differences are in the underlying nav aids, not whether the procedure is straight in or circle to land. Now, having said that, I know some examiners are willing to count one LNAV and one LPV to 400’ or greater minimums as two non-precision approaches, and one LPV to 300’ or less as a precision approach, all three ‘different’. So really you need to check with the examiner you intend to use.
BTW, CFII’s giving IPCs are bound by the same rules. I work around that (if the airplane has only gps) by simulating a gps failure - I hand the pilot my handheld nav radio and ask for a vor approach. If you have a DPE who insists on different nav approaches, ask him if this is acceptable to him.
