Sadly, the Dev of RiF - talklittle went to Tildes.Net, which while open source and donation run, is not decentralized/federated
So unless someone else makes something similar or the talklittle also decited to use Lemmy at the same time, I'd say it's unlikely.
But currently there are around 10 apps in development for various platforms for lemmy - I myself will try Sync For Lemmy, along with any others I can find to see if I can find one that suits me better than Jerboa or a PWA. (Currently using both)
