I would find that cringe worthy.
Even before the annoying usage in political non-discourse began there was the phrase about "special snowflakes" and I don't think you can disconnect well from that meaning. Snow would be cute. I would be shocked to see Snowflake on a boy. It seems kind of small and chirpy and people don't usually go that way for boys. Snow is nice for either gender though I would like it better on a boy.
If I go for nice combos
Snowflake
Eliana or Snowflake
Leland
If I go for what I'd expect
Snowflake
Sunday or Snowflake
Noelle
~Anna~
