Is this a utopian goal!?

Hi you all AudioPhiles and VooDoo Masters of the Universe!
As a "reminder," I have done the cap mod and am feeding audio in through ACC2 and this does work for me well. Also, I am using "0" as the TX shift which is way better than using 100Hz on my Kenwood TS870.
TS870s having been manufactured in different years have been known to be able to transmit at wider than 4 kHz TX transmit bandwidth.
The jury is out on this I assume, but some audiophiles have told me that depending on the S/N, the firmware in ROM +DSP (TX filter pass-band) may impose a hard TX bandwidth limit that you just can't exceed no matter what you do with outboard audio processing gear! I am wondering how some have been able to do that with TS870 rigs with a slew of different S/Ns?
Should I be boosting (narrow Qs) different frequencies such as 4kHz, 6 kHz although 6kHz appears unrealistic! I know that studio (yes, I DO realize that we're talking radio here NOT studio recording!) engineers talk about "feathering" that is to say for instance boosting frequencies (I assume using narrow Qs) within a given frequency band with a string of frequencies involved. I might imagine that I could boost 4kHz (15/60 octave), 4.5kHz (15/60 octave), 5 kHz (15/60 octave) for instance but then the question becomes, will I be able to use the compressor to make sure my ALC doesn't go crazy WITHOUT killing the dynamics of the audio? I could probably boost high frequencies well using EQ but then I would sound like a machine as I would need to compensate for those boosts with the compressor : (((( Seems counter-intuitive to first boost highs (albeit this is a static function) and then COMPRESS them (dynamic feature versus static).....
I would appreciate some common sensical advice!
