Janna and Nami only have mobility in common and don't contribute the same exact things to their lane. For instance Vayne has to get into shooting distance to trade. Janna doesn't heal but her shield makes that trading possible along with the bonus AD it grants her a chance to get more health back based on the life steal she's currently rushing.

Meanwhile Caitlyn has an generally longer range than any ADC and while you could give her Janna's shield to let her do bonus damage Caitlyn doesn't have to trade with anyone other than Jinx and Kog'maw. Because you get free trades you don't need the shield but you do need to keep them in range hence why having the slow on Nami's E serves her better.

Range and zone makes Nami stronger, not necessarily pure harass or sustain.

Lucian range is low and he can't spend all lane casting spells without running out of mana. Karma and Lulu are better choices bcause of their decent on cast mobility and shields and Lulu is even better for Lucian because she gives him additional power through Pix and additional crowd control to kite the enemy which he needs.

But even then I would say that Lulu is better with Varus due to Varus needing mobility for the casting of Q as Lulu's Whimsy can directly offset the penatly of casting it making it far more effective at landing and much harder to dodge to speak nothing of how Varus could use the mobility for escaping.

There's a reason why people aren't using these combinations despite how effective they actually are. It's due to the concept of a kill lane being easier or a sustain lane being safer. A poke lane is inbetween those two and you have to be effective at understanding that strength to really win that lane.
