Only VIP no Interface IP

Why is it not possible to only assign a CARP-IP to a Interface? We have have 20x /30 Network Interfaces. To use CARP we need to resize every network to /29.
It would be useful to not assign an ip to the Interface and only create a CARP VIP.
Is that possible anyway?

Cause the interfaces which are sharing a CARP VIP must be able to communicate over Layer 3. So they need to have a unique IP each within a common subnet.
It's possible to assign IPs out of a private subnet to the interfaces with some drawbacks.
You may find threads discussing that topic here in this forum when you search for "CARP with only one public IP".
