Killer Frost transfer to Caitlin. Oh it certainly is. If it would become a thing, it would just be a dysfunctional relationship that would not work, but is still forced on us just like Olicity. A world where Caitlin is with Barry would mean she would be angry with Barry even more than she already is because her boyfriend went back in time and changed her life. Causing tons of problems for the seasons going forward. As they have an on/off relationship fans beg to be over. Also Iris would be killed by Savitar in this version because the SnowBarry fans would feel threatened by her ruining their "perfect couple".
 * Caitlin tries to give birth and transfer to Killer Frost.
 * Killer Frost: Oh. Hell no. She got knocked up and she wants to escape. This not gonna happen.
 * Caitlin" Why am I back?
 * Ronnie: Killer Frost said Hell no.
 * Caitlin: Ice cold bitch.

That isn't how pregnancy works. Killer Frost is essentially another persona. A symptom of a meta version of multiple personality disorder. So she could not switch the pregnancy between the two of them. They are both stuck with a kid if they had unsafe sex.
