Should have ended with Season 4

So the last few episodes of Season 4 where Fiona gets arrested is a huge story changer showing the show will continue. But the ending of season 4 could have been a perfect ending if some things were changed

1. Fiona stays and grows at the cup job to provide for her family and stays with her boss
2. Lip excels in school and graduates
3. Ian stays in the military and succeeds (The whole story of him taking Lips SSN shouldnt happen) sending some $$$ home to the family to help. Between Fiona and Ian $$$ they could have a good life
4. Carl and Debbie get to grow up with Fiona having a stable job and insurance
5. Frank Dies from Liver failure.
