I'm not clear how Dragon Knight went down over here since I didn't pay much attention. It's not a bad idea, it's just going matter of

A) Set itself apart from Power Rangers
B) Finding the right source material and gimmick

Ryuki was a good choice due to the large number of Riders and the diverse characterizations and interactions that would have offered, as well as the card gimmick (who doesn't love card gimmicks), so Gaim would be a sound choice since it has a similar number of Riders- though many would likely be turned off by the whole "fruit armor" thing.
