Considering this hack might take anywhere between 2 and 4 years, by the time I'm finished I imagine 4th gen hacking will be much more popular. So we'll see about a sequel then.
If by dinobeemon's other digivolution you mean GranKuwagamon, I will be including him in Kuwagamon's digiline. Although both are canonically correct, I don't agree with it personally.
Dinobeemon has everything to do with paladin imperialdramon lol. Stingmon and ExVeemon DNA digivolve into Dinobeemon, then Dinobeemon digivolves to Palidramon, then to Imperialdramon, and finally to Paladin Imperialdramon via DNA digivolving Imperialdramon with Omnimon. It all starts with DNA digivolving Stingmon with ExVeemon to get Dinobeemon on one end, and MetalGarurumon with WarGreymon on the other end. So yes Dinobeemon is definitley necessary for Paladin Imperialdramon's digiline.
Puttimon will either digivolve to viximon, tokomon, or nyaromamon. Those three respectively lead to Renamon, Patamon, and Salamon's digilines, where you will get Kyubimon, Angemon, and Gatomon from. So on and so forth, with potentially other digilines along the way.
