AHQ:Who does Luis I marry?

In my timeline, Spain and France find themselves on opposing sides in the Cossack Revolution, a war that goes up until 1727, and Spain is also against Austria in this war. OTL, Luis I of Spain married Louise Elizabeth of Orleans, the daughter of the de facto french ruler at the time, in 1722. I doubt Philip V would marry his firstborn son and heir to the daughter of a man he’s currently at war with, but there don’t seem to be a lot of options. I’d imagine he’d want the marriage to happen before Luis reaches adulthood as he’s the first Bourbon born in Spain and securing a stable succession is imperative for any new dynasty. I also doubt he’d marry a Protestant (all of Spain’s allies in this war are either Protestant or Muslim so idk whether a marital alliance is on the cards- I’m leaning towards not).

I’ve seen lots of matchmaking on this site, so who do you think is a viable option for Luis I of Spain?
