Alfred King of Greece, King William where?

According to the Wikipedia page on Alfred, second son of Queen Victoria, the Duke of Edinburgh did not become king of Greece because of the objections of the Queen, who wanted his son as Duke of Saxe Coburg Gotha. But in 1862, Victoria had 2 other sons (Arthur and Leopold) who could inherit the duchy.
In a scenario where Alfred becomes King of Greece in 1863
Where Willian of denmark could be King?
Also supposing Alfred married Olga Constantinovna in 1867, with whom would Maria Alexandrovna and Willian marry?
 
Well William of Denmark fell for the very young Olga Constantinovna - she is not going to be the obvious choice for Alfred in this scenario.

Alfred met Maria Alexandrovna at visits to his sister Alice's home if my memory serves (her husband was first cousin to Marie) and the two developed an attraction for each other though it took a long time before both parents agreed to the match - if Alfred accepts the Greek throne and his mother doesn't scotch it as in OTL then actually MA's parents might be more in favour than they were in otl. She will be Queen of Greece, won't have to play second fiddle at the British Court and her religion becomes an asset to Alfred rather than a hindrance.
 
As king of Greece Alfred would soon have to produce an heir. He would have started the search for a bride soon, in 1867, when George married Olga, Maria was only 14 years old, so I do not think she would be considered, just because of her age, although Olga was also 16 years old. her marriage) were more common 16-year-old princesses getting married than princesses of 14, besides the fact that Maria was Emperor's daughter, which makes it almost impossible for her to marry so early. Maybe Eugenia of Leuchtenberg or Catherina of Oldenburg might be a good choice.
 
You'd have to find a way to get around the treaties that vetoed Alfred being made King of Greece IOTL - that was probably a bigger issue than any personal objection that Vicky had with his accession.

They (Eugenia and Katharina) WERE on the list of brides considered for Affie. But as stated, he wanted Maria. Not to mention Victoria was a bit worried about how the country would react to her having a Napoleonide daughter-in-law IIRC. But if Affie never meets Maria, or there's a reason she's unavailable - Eugenia or Katharina are the likeliest Romanov proxies. Of course, if Affie dithers until 1866, Katharina's death removes her from the table (and jusging by Alexander II's remark to Katharina's sister, Alexandrine, when that lady complained about her husband's infidelity, he basically said "I don't/do you blame him?" So Kate might be too dull to capture Affie's fancy anyway).
 
If Catherine married Affie in 1864 - they could have only 2 daughter daughters (1866 and 1869) and Catherina died in 1869 - so he could fall in love with Mary and marry her between 1871-1873 or could he simply marry Olga in 1866 and Mary marry another pretender perhaps William of Württemberg might be interesting
