So you are not asking could you you are asking should you?
I love chicken head knobs but not sure they would look good on a Recto. Be fun to try nonetheless. Blacked out recto knobs would not look good imo. That said, recto knobs are a PITA so see the settings. You kind of have to tilt your head to catch the light just right and then turn the knob back and forth a bit to dial in.
All kinds of painful.
If I were to do mine I would consider the Mesa Mark type knob or MXR knob or the plain jane 'pointer' knob.
