some you can, some are more work as you'd need several sections and then you'd be sewing them together. Personally, I'd much rather work with templates and sew regular than paper pieced. But I don't hate Y seams either
When I did Sylvia's Bridal Sampler, it had a lot of templates and also some paper pieced. I did almost all of it by measuring the templates and rotary cutting the pieces, sewing and trimming to size. A few of the other people got real good at converting them to PP. They were all 6" blocks and a lot of small pieces to work with. Anael is quite good at it.
