not the dev so dont take my word for it but i assume all the frontend UI stuff is gonna be the mostly same, it's just the APIs being changed to Lemmy's
that's how Sync turned out
I think Rubén is working with boost for reddit as a base and modifying the API requests to accomodate lemmy ones so, if that's the case, the chances that this is actually posible are very high..
Let's hope thats the case!!
