I personally think that if anyone is marrying one of Victoria's kids it will be Clarence or York. Britain has already had a domestic marriage for Elizabeth and might see marriage to an alt Vicky a waste. Bear in mind the May of Teck scenario involved several foreign candidates either turning down the offer (Alix of Hesse and Marie of Coburg) or being rejected by Victoria for not having the right qualities or being too ugly. If William is less focused on looks and/or Elizabeth less picky then many of the candidates rejected for Bertie come into play and he likely marries Alexandra or one of the rejected German candidates.
According to the astute voices of Wikipedia, the following princesses were in the running for Albert Edward and thus they, or their ATL sisters, could be potential brides for William: Marie of the Netherlands, Marie Gasparine of Saxe Altenburg, Elisabeth of Wied, Anna of Hesse Darmstadt, Alexandrine of Prussia, Alexandra of Denmark, Wilhelmine of Wurttemberg, Catherine of Oldenburg, and Augusta of Schleswig Holstein. Obviously, Alexandra will continue to be a big catch, but I could see the attempted British- Dutch match part 3 given Marie's intelligence and wealth (she was apparently rejected for being too ugly IOTL, but again maybe William won't be so looks focused?).
Based on the descriptions of the boys the best chance to have one of Victoria's girls in the royal family is to have foreign princesses find Clarence a dull navy man who's only a 3rd son and, at this point, has several nieces and nephews via Wales and York pushing him down the line of succession. With a lack of candidates and a desire to get her son married off (plus get cousin Drina off her back), Liz offers up an Alt Beatrice to be Duchess of Clarence, giving him a popular English bride without sacrificing diplomatically (nor risking the main line being populated with hemopheliacs.
