Rookie lebron and showdowon lebron combo?

[lion23]

Is this combo doable? Im trying to make a legacy lineup for 3rd acc and wanted to have at least 2 lebrons.

I want to say it's more likely doable than not, but I can't guarantee it. Royalty & Showdown Lebron can be put together, I'm also running POTG and All-Star MVP Lebron in the classic lineup along each other too.

It's not.
