Trust me if I had Bitcoin Core on my computer I would have tried it. I can't help but think there's a way to do it through a push tx service. And I wouldn't want to pay a miner to include it if its malformed, which may be the case. I tried doing it through here:

https://bitaccelerate.com/pushtx/

which says this at the bottom:

"Тhіѕ ѕеrvісе іѕ uѕіng thеThis service is using the "ѕеndrаwtrаnѕасtіоnsendrawtransaction" mеthоd оf thе Віtсоіn Соrе сlіеntmethod of the Bitcoin Core client.

But still got an error.

For reference, this is the unsigned transaction I was trying, would be grateful if someone could analyze it and tell me if something is wrong:


This is the error I get from blockstream.info/tx/push when attempting to broadcast the signed transaction:

"sendrawtransaction RPC error -25: bad-txns-inputs-missingorspent"
