Of all the adcs with low (<550) base range, I'd only call graves and maybe quinn bursty. The others (Kog, Sivir, Jinx, Urgot) have different tradeoffs for their low range, be it range steroids, innate tankiness, or defensive spells. Keep in mind that graves passive also makes him a fair bit tankier than other adcs, which is one reason why he can operate at low ranges. I picture post range nerf Lucian being very similar to Graves, but with far more sustained damage and comparable mobility to make up for his lack of tankiness. He's also got a more optimal build path for a low range adc (BotRK, Triforce, and Ghostblade synergize much better with Lucian's kit than Graves).
