If you are planning on scorching them to death, hard-rezzing one giant piece of ice is doable. You can bounce it back to go +14 the turn you need to kill them. In the meantime, well, you have a giant piece of ice somewhere that doesn’t die if they break it.
That said, moistloaf’s point is good, it’s an interesting way to look at it. Restructure gives you 5 credits per card. Curtain Wall + OAI gives you 6.5 per card, less if you’re running Hadrians too.
The version I’ve been trying recently runs 3x Archived Memories to get more mileage out of the OAI and get that credit-per-card up.
