The "Character Vocal Series" are based on voice acting or the act of one vocal provider each.

The trouble I will point out with young boys is their vocal is subject to change over the age of 12-18 dependently. Voice actresses often voice boys because they can do the vocal range of a pre-puberty boy but because their adults never have to worry about their voice changing. You can hear the impact on Max from the English dub of the original Beyblade series, each season his voice changed slightly as his provider went through the voice break stage. Harry Potter's actor in the movies also had his voice break halfway through the first movie and in order to hide it they had to manipulate the rest of the movie's sound, it was bad because Harry was suppose to be 10 years old and wasn't at the age the voice normally breaks. Phineas and Ferb gives us our third example if you watch season 1 and listen to Phineas' voice.

But yeah, even though the voice actress can do the range, being an adult female things won't match. The pre-puberty male vocal is a bit different to an adult females vocal, if you compare Len to Oliver. But if Oliver's provider was to do a voicebank now, he wouldn't sound the same at all because of puberty. Though I will say the CV series was never intended to be carried on beyond Luka originally so they had no long term plan for more Kagamine voices. The popularity of Miku basically changed everything.
