Could happen! I think it's cool too. It's just kind of at odds with making more pedals, because it's so much more time-consuming and I can't really outsource the paint part and have it look similar. So the more I pursue the art aspect, the fewer pedals will ever be in stock.
Looking at the numbers of people on the mailing lists for each pedal, right now I think making more pedals is probably the thing to focus on, but I want to do a bit of both. The Subterrographs were engraved, for example.
I am sure people would pay more for the extra work required.
I say go for it!
