1 VIP Handling Multiple Web App Services

I am in the process of migrating many web app services in Azure, behind a pair of F5s. Most of these web apps are behind an internal ASE. Any web app behind the internal ASE will respond to the same IP address. We are using a wildcard SSL cert which will be applied to the majority of them. What we're planning on implementing is:

• Whichever web apps ends with https://x.x.army.mil; we will attach them to the same VIP, using the same client/server SSL profiles, and a rewrite profile which will rewrite the client URL to the correct server URL.

I would like to know is there any downside to this solution? We are using auto SNAT, which I believe allows us 65535 connections to this 1 VIP. Not entirely sure if this is true.
