I'm having similar issues with my cat, and this sounds like a genius solution. No issues pooping in litterbox, but perfers books or bedding to pee on. According to the vet(s), he's in perfect health, and he has multiple litterboxs in different locations, so I guess he's just a weirdo. Dog pads in a litterbox seems like the perfect solution.

She'll also pee on random locations if she's angry at me (like when I come back from traveling). She will pee in the bed as a tantrum. Look at something that may be weird. What helped.for me is that I started giving her special atention time. Everyday we have our brushing ritual where.she comes to me and I brush and pet her for how long she wants, usually right before bed. I feel like she is less anxious because of the routine.
