Former beekeeper here.....I can't help you with the font.
Honeybees don't build their comb that way. There is always a hex point at the twelve o'clock and six o'clock position. It's not by mistake. This engineering work is part of several amazing factors that permit the water-like liquid nectar to remain in the cell until it eventually thickens into honey.
See if your client will allow you to rotate the comb 30 degrees one way or the other.
