Breaking a trend

In my fictional sibset I have [name_m]Ernest[/name_m], [name_m]Eugene[/name_m] and [name_m]Edward[/name_m]. I really like the set but I want to make it bigger and other boy E or girl names don’t really have the name feel to me. Would it be weird to break the trend? Could I use a different letter for girls?

What I feel flows but starts with a different letter:

After three with the same letter I would stick with the theme unless it’s for girls names. That being said, I think [name_f]Philippa[/name_f] and [name_f]Nellie[/name_f] go well with what you have.

Some suggestions:
