Once you have a tool that uses pgp with keys you provide, and encrypts messages in normal chats, changing the actuall message format would probably be easy, so there's plenty of room for adittional steganography. Images would make for a perfect cover, with something like last-bit steganography.

But, I hope it won't come to that.

They will have tools to scan for steganography. I bet Palantir or some other dodgy tech bro company is more than happy to sell something like that to them. And with PGP's not only strong encryption, but just as strong authentication, they'll have no problem whatsoever proving that it was you who sent those illegal encrypted messages.

That's true. I guess that in this case, your best bet is (assuming you don't have something so illegal to hide, that they do want to expend large amount of resources on you) to just go security by obscurity, and have some kind of obscure custom steganography that's not widely used.

And for PGP - I though that there's a difference between signing and encrypting a message, and when you only encrypt and don't sign, they can't attribute the message to you, assuming they don't have your private key or the original plaintext? Or is it possible to attribute a encrypted message using only public key and cyphertext?

I'm not entirely sure, and was more thinking of the standard application of PGP where encryption and signing go hand in hand.
