That I understand, and you don't take out any of the magic, just rather focus on the rangers having actual lives and actual problems fists and giant robot dinos can't necessarily fix.
Ironically, that's exactly what the next Sentai after Go-Busters did. Kyoryuger had a 30/40-year-old guy who was helping his sis raise his niece. Though that's as far as that show went. It originally also had the rangers work separately, like, they don't come together to transform, but rather transformed individually then arrive at the fight which was actually cool and could help flesh out that exact idea...
Unfortunately, Kyoryuger was one of those Sentai/Ranger shows that also had a huge helping of "Huh? They're a team? NAAAAAH, the Red Ranger's the only ranger here!"
