Webflow with self hosted ghost blog using reverse proxy

Is there a way to have the home page hosted in webflow and site.com/blog hosted in another server? If I am using reverse proxy to achieve this - what should be my entries in the DNS record?
Also, which webflow ip should I use - currently I see 2 IPs in my hosted custom domain option or I can use any one of them?

Basically, the idea is to point @ record to a nginx reverse proxy server - then make ghost blog server /blog and rest to be served by webflow? Is this doable?

@pranay01 - Did you find a solution to this?
