It's A Wonderful Life is basically a modern take on A Christmas Carol, so you're still working with the same base concept. A very good and interesting concept. I see Katzman's totally unrealistic botched execution of the It's A Wonderful Life concept as the problem, not the lack of ghosts. None of what they showed as what would have happened without J.R. was realistic. Sue Ellen would have married Clint and been a stay at home mom. Gary would have been running Southfork with Ray and rasing Lucy with Valene. And Bobby would have been happy with Pam raising their children together and maybe running his own company.
