I did'nt want this to end up as another "go buy a grinder" thread like
yours and the 3000 others you refer to.

Maybe my question should've been;
Is it possible to deliver decent crema with pre-ground coffee on the
Rancilio Silvia?

If someone thinks this is possible, please let me know how and with
which modifications.

In my experience with my Silvia, it is not possible. Good crema, and
good espresso for that matter, is a function of brew pressure and flow.
Those are a direct result of tamp, grind and freshness.

The only way you could possibly get good crema from pre-ground would be
to buy it freshly roasted, ground to exactly the size and consistency
that your Silvia needs, and get it in the Silvia within minutes of
grinding.

We don't say you need a good grinder just because. We say it because it
is just a fact of life. And that holds true of any espresso machine
that doesn't used pressurized or crema enhancing portafilter.
