I don't think that we can presume that its redundant. Effectively you are still applying for an IMC rating and on a UK licence that's exactly what you would get. For the JAA licence then they will have to issue it as an IR/R on an EASA licence as they can no longer issue a JAA licence. In the absence of any other information I would just submit the SRG 1125. I wouldn't even complete the 1104.
