Sorry my mistake, I thought that you public addresses were 10.10.10.211/255.255.255.248 and 20.20.20.68 255.255.255.224 (and moreover I mistook the second subnet mask for the first subnet).
You will have just a couple of usable public IPs if you split it so it is not worth it. Other than that you can set up a host-to-lan tunnel, that will connect your servers wherever they are and provide with the public IP from your range.
