Only if investigators actually wanted to do so.
I'm more of the opinion that any lists that exist(ed) outside of Maxwell have been actively used blackmail material by the deep staters. The FBI files have been in the possession of the Rats for 4 years. Who could possibly believe they haven't been seriously monkeyed with? I don't know that I'd believe anything in them after the Rats have had them for so long.
Another possibility is that some evidence on very high profile targets may have been so valuable that it was not in Epstein’s possession, but rather held in secure repositories by his enablers/managers for timely use. You don’t store valuables in an outdoor shed. Just saying.
