Integrate Blazor components inside MVC .NET Framework 4.8

Title, is it possible to integrate blazor into a legacy project? My company wants to upgrade a gigantic legacy project (over 1m lines of code), but they want to do it gradually as customers are still using it and we can't just green field it, so going from framework to .NET 8 is a no go. I know it is possible in .NET Core but is it feasible in framework? The current proposed solution is iframe.
