WRT FAA Maintenance, dont be under any illusions, you may be able to adopt a FAA program, but you will need a suitable contracted organisation to implement it who will need manx approval, assuming your line maintenance is not going to be done by a member of that organisation, he/she will need to be licensed on type and have a manx validation. Otherwise you may under certain circumstances be able to have a non typed guy possibly perform certain tasks with an A&P but for each task he will need to have received training for each from your 145 place and he will need to be validated.
