Hi Jill! Check into Royal Design studios lace stencils! They have several to choose from and there is one that looks like a Doily! They also have how to videos.
Just realize when you add texture to walls you are stuck with it. So when you get tired of it or it's not what you really wanted, you'll have to redo the walls. Will also natively affect your resale value. Just stencil to look like it. Sounds pretty.
How about using paper doilies as stencils? https://www.etsy.com/uk/shop/ThePaperDoilyStore
I think you could find a great stencil to use. That sounds really pretty!
