It's not going to be possible because Apple hasn't come out with an equivalent to Gemini. It would be like if Siri also had full LLM conversation capabilities, and access to all your documents/email/etc, and direct integration to run web searches, analyze web pages, etc. And it's fast enough to have a real-time conversation[1], as if you were speaking to a human on the phone. Oh, and that's on my Pixel 7, which is two years behind.
