Of course it is.
If you would understand that SSB is simply audio mixed up to R-F, you would not
have this mistaken idea. We normally do it in two steps, audio to I-F, I-F to
R-F, but that's all it is, a frequency conversion.
Certainly, if you take a 2 KHz band of audio frequencies and run the result of
the first frequency conversion through a 1 KHz filter, you will band limit the
result. However, if you run the same product through a 10 KHz IF filter, you
will still get a 2 KHz wide result. The wide filter isn't going to magically
widen the transmitted signal.

Joe,
You of all people should know it's not the same as actually narrowing the
IF.
You should try both and compare.
