Is it possible to make WPF and WinForm friends with minimal effort?

Question

WPF

Colleagues, good afternoon. The question is from the category "for dummies", but I really want to get competent advice.
There is an application on WinForms F3.5 (niche CRM), which has already completely outdated interface for several years of development. There is no way to switch to a web application now, but I want to "refresh" the design and make the system more user-friendly. Is it possible to develop such "pretty" controls on WPF and make them friends with the business logic of the application, without spending too much effort on it. By little effort, I mean the cost of design, layout, creating the WPF control itself, and making it interact with other controls on the form.
