Cross Border Champions Super Cups

My idea is for two different countries to have Club Super Cups between their nation's champions.
The idea would be each year the champions of the two nations play a one match final, with the game held at one of the participating team's stadiums. With the host nation swapping each season.
The trophies could be held at men's, women's and youth level. And second tiers.

My idea would be for instance in football / soccer for club v club national champions;
Scottish - Welsh Super Cups.
Scottish - MLS (USA and Canada) Super Cups.
Welsh - Irish Super Cups.
France - Poland Super Cups.
Scottish - Irish Super Cups.
German- French Super Cups.
English - French Super Cups.
Norway - Sweden Super Cups.
Scotland - England Super Cups.
German - English Super Cups.
Italy - Spain Super Cups.
England - Italy Super Cups.
England - MLS Super Cups.
Spain - England Super Cups.
Greece - Italy Super Cups.
MLS - Brazil Super Cups.
Poland - Scotland Super Cups.
Greece - Turkey Super Cups.
Australia - Scotland Super Cups.
Brazil - Argentina Super Cups.
China - Japan Super Cups.
Denmark - Sweden Super Cups.
Poland - Finland Super Cups.
India - China Super Cups.
South Africa - Cameroon Super Cups.
Mexico - Brazil Super Cups.
French - Spanish Super Cups.
Switzerland - Germany Super Cups.
Austria - Switzerland Super Cups.
Hungary - Austria Super Cups.
Poland - Slovakia Super Cups.
Czechia - Slovakia Super Cups.
Andorra - San Marino Super Cups.
Portugal - Spain Super Cups.
Netherlands - Belgium Super Cups.
Bavaria - Catalonia Super Cups.
Spain - MLS Super Cups.
Portugal - Netherlands Super Cups.

This could also be done at other sports like basketball, cricket, rugby union, baseball, ice hockey, netball, field hockey, and volleyball at club sports.
