Is SJM ever going to write a prequel series? Spoilers up to book 4!!

Throughout the series we get a lot of lore, and history. I'm particularly thinking about how in ACOMAF there's talk of pre-acotar Amarantha, Jurian, Miriam, Drake-whatever his name is, etc. I thought maybe eventually we'd get these as their own books, the first war and whatnot? Has she ever talked about that in interviews? It would be fun to read.
