X509 certificates published in CT logs are "pre-certificates". They contains a poison extension so you don't be able to use them with your private key.

The final certificate (without poison and with SCT proof) is usually not published in any CT logs but you can submit it yourself if you wish.

OP idea won't work unless OP will submit final certificate himself to CT logs.

I didn't realize this detail, thank you.
