(I’m [name_m]Danish[/name_m] Canadian, but my family’s been in [name_f]Canada[/name_f] for 2 generations, so these suggestions may be outdated 
)
I think [name_m]Juda[/name_m] and [name_f]Mika[/name_f] hit all of your marks and fit well with your other two!
Some other ideas if you’re open to…
– names with different pronunciations in [name_f]English[/name_f] and [name_m]Danish[/name_m]: [name_f]Alva[/name_f], [name_m]Ilya[/name_m]
– names that end in an A sound: [name_m]Pelle[/name_m] / [name_f]Pele[/name_f], Alfr
– names that have an a sound ending nickname: [name_m]Mads[/name_m] “Messa”, [name_m]Jens[/name_m] “Yessa”, [name_m]Nils[/name_m] “Nisse”
