Hello HTH :D
Getting much closer,
( I say this in confidence - so everybody else look away )
I was thinking of the early Indyguitarist Plexdrive pedals, before they started using white powder coat finishes and adding extra decoration - or closer to your example, the way that the initial ' un-painted' limited edition MXR Zakk Wylde OD pedal ( raw metal, blue LED ) - looked.
I like rounded edges and simplicity of design. Understated is always more attractive to me.
If anything, I like the sound of your boxes just as they are, brushed aluminium with creme knobs - a real touch of ' vintage ' in my books.
( although I do love Blue LEDs ) .
I always think that pedals and amps are like good quality clothes or cars, the variations and fads come and go, but the classics always look good.
