Unfortunately there is not supported as VPC peering is not transitive as explained here:
If either VPC in a peering relationship has one of the following connections, you cannot extend the peering relationship to that connection:
- An internet connection in a private subnet through a NAT device
Also:
Similarly, if VPC A has a NAT device that provides internet access to instances in private subnets in VPC A, instances in VPC B cannot use the NAT device to access the internet.
