As Neptune transits in Aquarius, conjoining your composite Mercury in Aquarius, you can anticipate an intriguing fusion of subconscious wisdom and intellectual stimulation influencing your shared communication. This might translate into some profoundly spiritual dialogues, in which you, collectively, have the potential to explore realms beyond current understanding. Expect to have your assumptions and ways of perceiving the world, challenged, yet enriched.

Transits of Neptune tend to blur boundaries, inducing subtleties and nuances into your collaboration. In your case, especially, this transit will bring forth submerged truths and might stimulate psychic insights enriching your shared communication. Equally, be aware of the common Neptunian pitfall of miscommunication, based on illusions or misinterpretations. Encourage transparency and vigilance in your discourse.

With Mercury in Aquarius, you already have a natural predisposition towards unconventional thought and progressive agendas. Combined with Neptune's idealism and spiritual impulse, this period could see you exploring more radical or innovative ideas together. This could also extend to sharing a communal vision or carrying out altruistic activities.

However, Neptune's dreamy energy can sometimes lead to a state of confusion or foggy thinking. While the realm of possibilities will seem infinite, grounding your thoughts and ideas into something palpable can often be challenging under this transit. Thus, duality will be an inherent theme - aim for balance between cerebral and intuitive understanding without indulging in extremes.

While Neptune is known for disillusionment, there is also an overwhelming aura of mysticism and spiritual enlightenment it brings along with its transit. As you embark on this journey, embrace the unknown and surrender to this cosmic wave with authentic communication, open-mindedness, and the shared curiosity that defines your bond. Remember, this transit is a door to an invigorating world of knowledge and consciousness for you both.
