If anything  tries to create harmonics by distorting the input (in any way)
it is going to HAVE to produce intermodulation products as well.

You could make a ckt to produce only even harmonics of a single frequency,
though.
And, in DSP, all things are possible.

Mind you, you could get an approximation by summing various different 
distortion ckts and cancelling out the most undesirable products.
I'd like to hear if anyone has done anything along those lines.
