I cannot advice you personally because you have a personal hearing loss specific to youself so only trial and effort will gain results.

You never said if the bone transmission on the deaf ear worked or not but if it does then for sure you have something to gain by considering a bone transplant in that side for hearing all round.

Yes moulds are uncomfortable to start with but with time they become very natural to the point you dont notice at all and glad of the hearing gain.

Sounds to me like you could do with some kind of equaliser software wise to get the sound to the right frequencies you can hear, only a suggestion but am sure it is worth a try.
