Is it possible to host a website on a computer but use the static IP from a vpn-server on a google cloud vm?

I have my website up and running on a google cloud vm. But it runs slow because i only use the cheapest one. Before upgrading the vm to a more powerful one, is it possible to host a website on my own computer using the IP from google cloud vm? I successfully set up a vpn server on it using softether (checking whatsmyip on my computer shows the public IP from google cloud vm). Any tips and help would be appreciated.
