You seem to have gone to extraordinary lengths to trap out each unwanted product, yet the final spectrum shows only -50dBc products. That seems a poor return for that effort in filter design.
I made a 5MHz doubler plus distribution for my HP5061. You can see the design at http://g4jnt.com/10MHzDist.pdf The doubler is a full wave rectifier and the filter a three section top capacitor coupled LC resonator. I achieved better than -80dBc rejection of the 5MHz fundamental and something like -75dB at 15MHz but this far down, measurement is quite a challenge. For most practical purposes these levels are more than adequate, but I do sometimes directly multiply up to 10GHz or higher, using this 10MHz source as the reference input to a PLL synthesizer. I think I've seen evidence that even -80dBc at 5MHz can introduce spurii at this level of multiplication, so really ought to be aiming at -100dBc - but that woul dbe impossible to measure with any test equipment I have. Even seeing -80dBc was a challenge.
