you might be better writing to the director of Manx National heritage to request that when the family history centre opens later this year with a new index to all parish registers referring to images of actual register pages and wills (which are currently being prepared for digitisation) that access be allowed (possibly on a paying basis) off Island; (much other info will also be available at the centre including a copy of the considerably more accurate index to episcopal wills held by Manx Museum)
