As someone who started the series and loves this game to death… I can’t say that makes much sense given the plot. Despite the similarities of FE2 and FE8, they’re not the same characters. …And why Riev exactly? He’s not like Jedah at all. He’s a heretic priest who was cast out of Rausten for worshiping Fomortiis and attacks Rausten to destroy the last Sacred Stone (and to get revenge on Mansel). He does not have any control over others, he just can communicate and control monsters. Lyon if anything is closer, but even they are vastly different.
