Dragon / Bug
The Dragon type only has one evolution line in RBY. The Ghost type is similar but quite broken; anything added from that would be dangerous, so let's look at Dragon. Dragon as a type is underutilised in RBY even on Dragonite itself. Its one weakness was made a kill button and the resistances were demeaned by the Flying type. It may as well not exist. A type ruined by time constraints and memory limitations.
Due to only having Dragon Rage, Dragon is a purely defensive type in RBY. Therefore, any Pokemon made for it should play into this aspect. I think the best option for this is Dragon / Bug, which adds a Rock weakness but also stonewalls SurfBolt Starmie, as it resists both of its attacks. It even gains a Ground resistance from the Bug typing, which means it can switch into Rhydon, Tauros, and a few others, although not completely safely due to the Ice weakness. This feels very balanced on paper, I like it a lot.
While strong defensively, this Pokemon would lack good STAB (Pin Missile, Twineedle...eh) and have to work around it, just like Dragonite. I think you would have to give it a higher attacking stat than usual somewhere...possibly Special, given this would likely be a defensive Pokemon itself. However, you could also work in BT89's Infested concept in giving it Bug STAB instead.
There's a ton you could do with this and I think people would generally just have a lot of fun with it. Ahhh, the Mega Flygon speculation days...
