There's also an another idea i have:Make Nobita immortal.He should go through universes and get op powers.And finnaly,when you think it's time to send Nobita back to his home universe,send him there with a body of an 10 year old.(His muscles should be still the same and he should have all the memorys and power and abilities.)
And if you don't want to send Nobita to other universes,just continue the plot with movies taking bigger role.(Note-He should also be on his home planet just doing his daily activities.But this time he should be extremely talented at everything.He should have extremely good qualities such as-extremely high intelligence,extremely high creativity,extremely high wisdom,extremely high intuition and extremely high imagination and more.)
