#122 the first concept i want to minimize the Howell/H part like you suggested, both in symbol and writing. so there's this GJ symbol but in between the G and J you can see H (negative space). the writing itself putting the Howell in smaller font above. it's a unique symbol, you can use it standalone for icon, favicon, application icon (if you planning to create smartphone application).
#123 is the variation of the same concept
#124 is possible writing minimizing the Howell part.
