Sure you can go though all that effort and replace the odd harmonics with
even ones that are harder to filter.? Also the added switching.
Or just include a series wide band pass pass filters?the sequence can then
be half octave or about 5 -6 filters for all of 1.5 to 30.
Cleans up the square enough to make it easier to filter and helps with the SSB TX spurs.
