You should just read Super and do PLs on that. It's on Mangasee in full color, plus you could actually justify the Cell Jr.s being almost 2x SSJ CG Goku :ha
I think there's just no real consistency. Piccolo and the humans could sense God Ki in the ToP and Trunks couldn't sense any of the Blues until he obtained SSJ Rage.
Toriyama's movies all sucked so far imo. BoG had too little explosive sequences and SSJG was underwhelming (didn't even get to use its FP), FnF was just trash and Broly spent too much time on the Bardock flashback sequence rather than on fleshing out Broly's character more, plus the resolution...
DB is sorely lacking in sympathetic villains, so my idea would be someone kind of like M8 Broly, but with actual loyalty to the "father." Since Vegetto fans get the shaft almost as much as Gohan fans pre-Super Hero, I'd more or less make the climactic battle an homage to the battle between Super...
The British are the most hideous people on Earth and they had to literally invade the darkies in India to get someone of another stock to fuck them :cena
