Theorically it's doable. But mostly No to your questions. IXP means Internet eXchange Point. So it is public Internet. Why do you want to use private IP address ?
Most RIR allocate /24 unit for IXP. For troubleshooting purpose, it is better to use public IP address as it is designed. Unless you want to have MPLS/VPN only connections, and use private IP Addr/ASN between them. Sharlon R.
