I've seen some clever or Rube Goldberg, depending on your perspective shaft extenders fashioned out of simple round or square stock and shrink tubing... I don't know how robust that would be long term (I would never use it in production). This is quickly becoming academic as digital controlled analog parts can be put where they need to be and control parts where they need to be.
The days of huge PCBs with lots of unused area has passed. IMO
Some of the old gear designs were mechanical marvels with strings, and springs, and pulleys, and levers, and ....

PS: Not to veer off into deep mechanical esoterica.. one of my mental exercises was to design a graphical interface for a parametric EQ. One of the beauties of simple graphic EQ is the visual representation of boost/cut and frequency by slider knob position. My paragraphic used a boost cut slider (moving up/down) mounted to two frequency slider wiper tabss (moving left to right for lower to higher frequency. Finally the Q was a rotary control mounted like a knob on top of the boost/cut slider, with a rack and pinion contraption on it's knob to visually represent narrow or wide bandwidth. (this could also be accomplished by a spiral slot that reveals a wider background color as rotated.
Obvious mechanical conflicts arise if frequency bands overlap, etc, and the cosmetic treatment of this is beyond my gadgetry skills.
