If you like the timing, i suspect you like the final timing and static. However reducing the initial will also retard everything.

What you need to consider is increasing the span on the machanical advance, so in the end you can you can keep the same final but have a little less static.

But first try using ported vacuum advance instead of manifold vacuum, like George recommends, that may be all you need to retard it during cranking.
