Is it possible to set CLI via the usr_preferences table in Kamailio?
Or any other way?
So that certain subscribers get there from-number overwritten with a
specific one.

You can use whatever mechanism you prefer to store users CLI's (so
their AoR username would be replaced by kamailio when, for example,
routing a call to a PSTN gateway). It can be a extra column in
subscriber table, an entry in usr_preferences or anything (LDAP,
custom DB table....).
Then you can add a P-Asserted-Identity header with retrieved CLI
before routing the INVITE to a PSTN gateway, or you can replace the
From URI using the UAC module.

Sure, you can script it in any way you like.
This is a working example from my system:
if (avp_db_load("$au", "$avp(s:allowed_cli)")) {
if (!avp_check("$avp(s:allowed_cli)", "eq/$fU/gi"))
{
xlog("L_INFO", "User $au is denied CLI=$fU\n");
sl_send_reply("403", "Forbidden");
exit;
}
}
You see, I'm rejecting calls with a CLI that is not allowed.
To override CLI you may use something like this, probably this should be
put directly before call to t_relay():
# Replace from if needed
if(is_avp_set("$avp(s:allowed_cli)")) {
uac_replace_from("","$avp(s:allowed_cli)");
xlog("L_INFO", "$ci : replaced from to
$avp(s:allowed_cli)\n");
}
