So, while nothing has been for sure decided on that Digimon front, there are a couple issues I have with your chosen line. Mostly, I don't see a natural progression of growth from Chibomon to Monodramon and likewise for Monodramon to the other two you listed (more Doumon than Kazuhamon). If you want to keep the Monodramon line, then I would be open to the Cyberdramon line. Or if that's not what you're wanting to go with, you could easily use Veemon's line of Veemon>ExVeemon>AeroVeedramon>UlforceVeedramon. My other issue is there seems to be a distinct lack of a champion form in the line you presented.
I just used a site that listed the various branch-evolutions, 'cause the other site only had one option of, and I did remember that there were crossing branches, and I thought that's okay. Sorry! Also I must've missed that Monodramon wasn't Champion. My bad!
Okay, so those lines seem a little better, but Hero has already claimed Lunamon. For your proposed Kudamon line, that doesn't seem to fit all that much. you could, however, opt for Falcomon's 2006 line with Ravemon as the Mega. I would also have to say no for Lucemon. Too evil in my head canon for to be a partner digimon. xD
I didn't see Lunamon being claimed already, that's my bad! And okay, I'll look for something else I like. :)
