Suggestion for Armor Digivolving

Well I kinda made this up on the spot so bare with me on this
First as any Digimon, get to the Ultimate or Mega levels of it, then use a Generation Gem to return(or become) the In-training state of a Digimon who can Armor Digivolve, become Its Rookie State and (After Quest or Finding It) use a Armor Digivolving Digi-Egg to make that Rookie into a Armor Digimon
For Example: Tokomon -> Patamon -> Angemon -> MagnaAngemon + Generation Gem -> Tokomon -> Patamon + Digi-Egg of Hope -> Pegasusmon

You Would Stay As the Armor Digimon Unless You Use a Generation Gem
As To Why You Would become a Ultimate or Mega First, is for the Stats

Thank you for reading this and I'd hope To get some feedback

Doesn't sound convincig. Pretty useless actually, since everybody would rather have mega digimons.
