Just because you prefix your request with your knowledge of Khaled's opinion on the situation, doesn't make it any more likely to happen. Khaled has never indicated anything that might lead you to believe he would port mIRC to another platform. He mentioned he "wants to" port to multi-platform, but this would probably never include platforms such as iOS or mobile devices, since "multi-platform" applications are strictly banned from being on Apple's app store (they must work exclusively on iOS) and I don't know of any "multi-platform" languages/frameworks that work across desktop and mobile envrionments alike. Khaled is not interested in maintaining two versions of mIRC-- he's made this clear in the FAQ above.
Furthermore, there are IRC clients for the platforms you mentioned. Use those. You really don't need scriptability on iOS, for instance, which is the one feature that makes mIRC stand out from the others, so I'm not even sure why you care about that one in particular.
