perhaps a letter to Tony introducing ourselves as a collective of shareholders (counter signed by all and including HINs) would suffice at this stage. we could invite him (or another company representive) to meet with us informally (in person or over phone) for a meet and great and casual (and confidential) chat

Easy, fast and low key, but effectively highlights our presence to the co. Our shared voice and HINs would speak for itself
