RiD Megatron isn't a reinterpretation of G1 Megatron. He was originally an entirely separate character called Gigatron in Japan, but Hasbro renamed him Megatron for RiD.
They could even be voting for Energon Downshift (who was called Wheeljack in Super Link ;)) - then could that, by extension, expand to G1 Downshift? And if G1 Downshift seems too obscure a character to be considered for the Hall of Fame, let's not forget the whole "Erector" incident. <shudder>
