If you're still interested in feedback on these...
Geoffrey Rhys - either I'm saying them wrong or they run together at least a bit (rey/rhy).
My favourite is
Ezra Luke, but I actually don't want more people to use
Ezra, since it's suddenly gaining popularity! When I named my son
Ezra, no one else was using it, and I liked it that way! :P
Beckett Alexander does feel a bit over the top, as does
Isaac Mercutio (though I assume that's rather the point of Mercutio).
I just tend to find
James boring no matter what, but it combos well as a middle.
I don't see a problem with
Rowan Elijah? And I just really love both names.
