I love
Luka and
Alexander separetely but not really together (it's not bad though).
What do you think of:
Luka BenjaminLuka BraedenLuka EllisLuka EthanLuka EvanLuka GabrielLuka GrantLuka JadenLuka JamesLuka JonathanLuka JulianLuka MasonLuka Monroe Luka Ryan
But if you really love
Luka Alexander , then I'd write it "
Lukas" and pronouce the "s" which would make the double "A" sound less bothering.
