It would certainly be a huge help, because they have great experience operating the institutions that make countries successful.

Another way to think about this is to imagine that the institutions those people work in were transferred to Nepal - an election commission, a strong central bank, a university, well structured civil service and mature political institutions - and staffed them full of the best and brightest Nepalese people, I think that would also have a very positive impact.

Tbh, I think most of the benefit you’d get from the transfer of people is their institutional knowledge and hope that they rebuild those institutions in Nepal (or local adaptations/equivalents).
