even a max size context window is what, ~1M? iirc tokens are generally part of a vocab of size ~300k. Assume no compression before the encryption (no clue if this is true, but compressing text before encryption can leak info regarding the message, namely how compressible it is), that's \log2 300k ~ 18 bits per token, or ~2 bytes. So each "turn" would involve ~2MB extra in each direction. And again, this is assuming max context.

seems plausibly fine
