Why? Henry's not likely to need Cleves and Bavaria on his side ITTL
Bavaria is admittedly a little less likely, but I still think Cleves is pretty plausible. Keep in mind, William married an Austrian Archduchess IRL - so England's ties there wouldn't harm any potential match
Not only is he much younger, he's not likely to even succeed as king. Especially since you have her older sister marrying his uncle
His brother Louis has died at this point, making him defacto second son. Plus that uncle would die a few years after the marriage date IRL - whether or not he is longer lived ITTL, I didn't picture him succeeding regardless. This means, a generation down the line, a similar match is struck, and just given the age difference between Henry's youngest and oldest kids, there is a sister still of 'breeding age' unmarried
These two hated each other...
Yet both Henry and Elizabeth considered marrying either them or close family - even if they have sisters as wives, that doesn't mean they have to get along
Are you assuming they elope? Who would approve of this ever?
This is meant to be synonomous of Elizabeth's relationship with him IRL. A very questionable match morally, but even some of her close friends encouraged her to marry him
