I’m afraid your hopes will be dashed because you will have to declare your ban in any UK visa application. UKVI takes previous travel history into account when assessing applications, a ban for deception makes it unlikely your application would be successful. In case it helps, you should be aware that the UK and Ireland share immigration data https://www.ein.org.uk/news/home-office-share-immigration-data-ireland-under-new-memorandum-understanding
