Silverfox: Can I make a Barber Half Gainer?

[jamiefbolton]

I like the LTD but I came across the Barber Half Gainer and wondered if I can change some values of the Silverfox to get a bit more mids back for a thicker sound. Thinking of getting 2 PCBs and basically creating two channels with the second channel having a bit more mids.  Good idea?
