Could Lidl support WERO as part of Lidl Pay?

I noticed Lidl Pay today, but it only supports Visa/MasterCard, at least in my country.

My banks don't support WERO yet, but I was wondering if there are any technical impediments to using WERO as a payment method in Lidl Pay.

If not, it seems like an easy win to push Lidl into WERO.
