Forum:Order of the knights

I recently watched Digimon Fusion season 2 (yea, im late) and it appears there isn't much talk of the order of knights, I noticed 90% of the knights are digimons in their rookie, or xros digivolutions also, alot of them are from Digimon : Digital Monsters, with Ken, TJ, Kari and the others. So that brought up a little idea to my head Could some of the digimon from the order of knights be from Digimon : digital monsters? Like Gatomon, Agumon, Greymon, Birdramon, etc? As there has been other mixtures of the digimon series merging with their other series many times before. And thats all I wanted to bring up.
