I think your first names are too similiar for twins, or ever siblings. Kyra and Kiera are almost the same name. Ditto for Blake in Blade. In addition, Blade sounds plain violent to me, sorry.
I like both girls names and Blake, though. And I think its cool that you are passing on your name to one of the girls as a mn. My childhood best friend's mom did that, and she was veyr proud that her mom's name was her mn.
I like Leander, but without the random capital letter. Blake Leander sounds nice, imo. :-) I like Blake Leander and Kyra Angelique a lot.
There are plenty of ways you could honor your husband without being bland or common. For example, one twin mn could start with a D, the other a J, and then he would have a DJ of sorts.
I'll try to find a few lists you might enjoy later. For now, I am off to watch Lost!
Good luck!
