3.55 can decrypt read and install 3.56, and we have all the keys for everything 3.55 can do.
I mean logically, 3.55 can make sense of all the files contained in the 3.56 PUP, so all the things needed to make sense of the 3.56 PUP are either already contained in 3.55 or are at least readable in the 3.56 PUP.
That said, there really doesn't seem to any point in 3.56 CFW. With the remote code execution, there's really no way to beat that, and the only advantage 3.56 has over 3.55 is PSN access. Since there's no good way to beat that, there's no real good reason to bother making a 3.56 CFW since even if you did you still wouldn't get PSN access. Aside from PSN, 3.55 can do everything 3.56 can, so why bother?
edit: Oh, I'm stupid and forgot how encryption works for a second. Of course we can decrypt everything in the PUP, but we won't be able to reencrypt because we'll never get the private keys.
No, you can't re-encrypt them using 3.56, but nothing is stopping us from patching the loaders that do those checks.
We need lv0 and possibly the hv private keys, though.
At that point, we need to patch the appropriate checks and rebuild from the ground up. Lots of work, and beyond me, but there is no reason why it can't be done.
Personally, I think Team fail0verflow should lead the effort, since they taunted Sony with the whole "Epic Fail" and "we pwn you" garbage at the CCC Conference. They should back up their words with action.
Graf_chokolo and a hacker who must not be named would probably need to be involved, as well, as they may possess the keys needed.
In short, fail0verflow was right in some ways - Sony can't change the lowest level keys, but then failed to deliver those lowest level keys that we need. If we get those, it truly is game over for Sony... all they can do is make busy work for hackers to analyze and patch subsequent FW releases.
At this point, though, you undoubtedly are correct about the fact that people will not be able to update from OFW 3.56. People should avoid anything "fresh" from Sony from here on out.
