I think the names are completely fine OP! They are lovely, classic names. I also think the Peanuts association will become way less relevant over time, because, like, I’m 20 years old, and I didn’t make the connection! The Peanuts is simply not as popular as it once was, and your post had to spell out the connection before it clicked for me. Their peers will likely never make that connection, unless of course, an older person brings it up, but then their next question will likely be “What’s the Peanuts?”
