Cross Border Cups Between Scotland, Wales, England and Ireland at Club Level

Cross Border Cups Between Scotland, Wales, England and Ireland at Club Level.
I would love it if we had more cross border cups between the club sides of Scotland, England, Wales, Northern Ireland and the Republic of Ireland.
I do not want the British and Irish Leagues to merge, as that would destroy our football history, and national identity.
I want the best of both worlds, where we keep our own leagues, and European football. But on top of that have cross border cups, between club sides from Scotland, England, Wales, the Republic of Ireland, Northern Ireland and Cornwall.
That way clubs in the Celtic nations would grow bigger with competitive games against sides from the top English Leagues.
I do not want the Old Firm and other big Scottish clubs to join the English League, as that would weaken the Scottish League.
If the English clubs could play Scottish, Welsh, and Irish sides it would increase TV revenue and attendances in the Celtic club sides. So by having higher revenue they would be able to do better in Europe.
Imagine games like Aberdeen v Newport County, Glasgow Celtic v Man Utd, Liverpool v Glasgow Rangers, Coventry City v Inverness CT, Ross County v Wrexham , Connahs Quay Nomads v Cork City, and Luton Town v Dundee United.
I think this would keep cross border travel as a good novelty, without becoming monotonous.
