Assuming it's this one , then, yeah...!
I did some serious due diligence on these books myself, as the books looked gorgeous. I had considered the viability of removing the books, restoring the mega-keys, and potentially selling off the other books as they are. I decided there was just too much risk involved, and I decided to chase something else instead (potential resto was a "maybe" depending on page quality, and the books would inevitably be labeled "TRIMMED" even if the missing edges were all replaced). In the end, those books went much cheaper than I anticipated, and IMO if you can get a beautiful bound volume of 25-48 for the same price as a restored Tec 27, then that's a sweet, sweet buy right there. Jealous!
