Royal-Royal marriages today

[Hereditary Mapmaker]

Assuming that current succession laws apply and if the dynastic requirements of religion and royal status were still in effect, currently every heir (except Alois of Liechtenstein) of the European monarchies would be excluded from the throne. If the dynastic requirements had never been "loosened", which of today's royal heirs and potential spouse/consort would make the:
(My picks are in blue)
Happiest union - Felipe, The Prince of Asturias & Princess Martha Louise of Norway (I KNOW...she'd have to convert, but there aren't a lot of Catholic princesses in that age bracket other than his sisters...GROSS!)
Strongest partnership - Crown Princess Victoria of Sweden & Prince Constantjin of The Netherlands (He definitely has some of the same facial features as the men she has been attached to. And I think they are both intelligent, good-humored and professional.)
Most incompatible/unhappiest - Prince Albert of Monaco & Infanta Elena of Spain (She definitely has a little more leche in her cafe than he likes. He probably wouldn't be faithful and I don't think she would like it)
Best looking - Grand Duke Henri of Luxembourg & Princess Caroline of Monaco (Given his similarity to Casiraghi and the beautiful children of that union, this might have made Luxembourg the best looking family in Europe.)
Best parents - Willem-Alexander, The Prince of Orange & Princess Alexia of Greece & Denmark (Lots of choices for both fathers and mothers in this category but very few could make a marriage. Given their age, temperament, and the loving way in which they dote on/interact with their children, I think they would have been successful together as parents.)
Most fun-loving - Prince Harry of Wales & Princess Madeleine of Sweden (May not be a good marriage match, but I bet they would be very entertaining.)
Most surprising/unusual - Prince Edward of Great Britain & Princess Stephanie of Monaco (I can't help it. It's just the most unlikely of couples I could imagine. Kind of like Porter Waggoner doing a duet with Queen Latifah. Can you imagine QEII's reaction to this?)

Feel free to add other categories if you like. I know there are thousands of possibilities, especially if you add in Germany, Italy, etc. I was just trying to keep it simple for me.
