Some people are simply more 'marriageable' than
others. It is because of their personality and characteristic they
exude, which creates such phenomenon. Marriage is like putting two
separate elements together and see how these different elements
react upon mixing. If you put something that blends well with most
elements, the product would be great or at least, it wouldn't cause
a huge explosion. Trouble arises when two reactive elements are
place together - you get a violent reaction.
Usually, those whom are less 'marriageable' are those Uranus-fueled
people - people who believe in individualism. They will score well
in achieving prestige, fame, glory and honor this world has to
offer, but in sacrifice, they usually gave up 'mutual thinking' for
Self.
You are asking if these two unknown elements would make a great
final product; nobody truly knows unless you make the experiment
happen and see how it goes.
Don't ask what marriage is all about without FIRST learning about
Love.
P.S: If you want to reduce the chance of a 'failed experiment',
make the effort to research those 'elements' you are dabbling with.

Cheers
