I suspect you will not get them via the Museum as they are very short staffed and it takes considerable time to locate a will (especially an Ecclesiatical will) on the microfilm - Brian's index gives the LDS microfilm number, it is relatively low cost (though you will have to wait) to hire this film and transcribe the will - there are many transcripts (well over 1500 including summaries) on my site and probably the same on Brians though there is a large overlap between us.
