I made a similar modification to an IC-735 to use the 250Hz CW filter
in SSB mode although that was a bit more complicated.
Let me know if you would like me to send the instructions.
Hey Ed. I now have the IC-735 and

First thing to do of course is make sure THERE ARE NO STRONGER ONES.
This can be done various ways. Typically, I use the variable
bandwidth tuning and IF shift to avoid strong signals. But, that's
rare to need to do
There is no difference between an RF gain control and AGC. AGC is just
Auotmatic Gain control instead of manual gain control.
The only way to copy a weak signal adjacent to a strong one is to prevent
the strong signal from affecting the AGC, and the only way to do that is by
using a narrrow

One more consideration is AGC recovery time.
Slow AGC and static crashes

A dual-loop AGC system may help and some high-end transceivers have this.

Dual loop AGC is a two sided sword. I have come to find better, and not
necessarily easier, to have low noise, low gain stages before the
filters that will not overload so easily.

Frank,
500 Hz is already a nice improvement with respect to 2.5 kHz..
While on the subject of filters, my current setup allows me to narrow
my SSB signal down to 500 Hz. Maxed out, the pass band is about 2.7
kHz, (3.6 on CW Wide.)
I have no optional filters installed, so I've been thinking
