Why make the aluminium parts if you are still going to end up using plastic?
Couldn't you just "back-countersink" the ones that you have?
Not sure about the process of making moulds from the aluminium masters either. I've only seen that done by making a rubber mould, into which you can pour resin. The resins that I have encountered would not be strong enough. It is a technique that rapid prototypers use to make mock-ups of ketchup bottles etc. Just for looking at really. The part that you are trying to replace will be a glass filled polymer and very strong.
