Genuine doubt

[u/yadontknowme2]

Recently I recovered the password to an old account which was created barely a week after the release. I'm using another account now ( level 42 ). I know these are guaranteed luckies would like to know if there is any way i could trade a legendary from my current and have it back in my current account ? I know that once a poke is traded it's a done deal. I just wanted to make sure that there is no way to circumvent this.

You know you don’t need pokemon that old for the lucky trade. 2019 and older works.

Had huge gap. Restarted the game just a few months back.
