I believe it is constrained to the normal SSB bandwidth of around 3 KHz
or less, unless using ESSB mode. However, I'm certainly not the expert
here.
For US hams, 47CFR97.307 begins:
"(a) No amateur station transmission shall occupy more bandwidth than
necessary for the information rate and emission type being transmitted,
in accordance with good amateur practice"
which would sort of preclude SSB much wider than what the K3 normally
does. However, I am neither a Commissioner nor a lawyer.
There were a few RCA Ampliphase 1KW AM transmitters made and they
sounded pretty good in a 10 Kc channel. One or two might still be
around and available. :-) Actually, I don't think RCA invented those.

If the FM filter is assigned to AM transmit, is there any improvement
in transmit audio bandwidth beyond 3 KHz,or does it remain DSP
limited to this relatively restricted range?
