Given the changes you have made to the SystemUI and framework, that is definitely not going to happen. Here are my notes, for the centered clock:

We need to divide the statusbar inside <LinearLayout android:id="@id/icons"/> into 3 <LinearLayouts> using the existing android:id and define android:layout_weight:

1. edit /res/layout/status_bar.xml

2. remove existing clock definition (with android:id="@id/clock")

3. Existing <LinearLayout android:id="@id/notification_icon_area">
define android:layout_weight="1.0" (it should already be there)

4. Create new <LinearLayout> with android:id="@id/clock" and unspecified android:layout_weight (ie: "0" by default)
<LinearLayout android:id="@id/clock" android:gravity="center" android:orientation="horizontal" android:layout_width="wrap_content" android:layout_height="fill_parent" >
<com.android.systemui.statusbar.policy.Clock android:textAppearance="@style/TextAppearance.StatusBar.Clock" android:gravity="center" android:layout_width="wrap_content" android:layout_height="fill_parent" android:singleLine="true" />
</LinearLayout>

5. Existing <LinearLayout android:id="@id/statusIcons">
define android:layout_weight="1.0"
define android:layout_width="0.0dip"
define android:gravity="center|right"

6. Existing <LinearLayout android:id="@id/signal_battery_cluster">
nest into the previous one with android:id="@id/statusIcons"

In addition, I was getting some funky background in the drop down notification clock area. I think it is now fixed:

In /res/layout/status_bar_expanded_header.xml replace existing line 2
<LinearLayout android:gravity="center_vertical" android:orientation="horizontal" android:background="@drawable/notification_header_bg" android:layout_width="fill_parent" android:layout_height="wrap_content" android:baselineAligned="false"
with
<LinearLayout android:gravity="center_vertical" android:orientation="horizontal" android:background="#ff000000" android:layout_width="fill_parent" android:layout_height="@dimen/notification_panel_header_height" android:baselineAligned="false"

For completeness, here is my full status_bar.xml:
