Lager fermentation schedule

So I have had a Baltic Porter (lager version of a porter) in the Primary for 15 days at 12C fermenting away.

Activity has slowed, the top yeast krausen has fallen and I have just racked it to a secondary carboy.

My plan is to:

1) slowly drop this to about 9C then mature for 10 days.

2) Over the next week slowly drop from 9C to 1C then leave a 2days.

3) Bottle.

I know this is a a little closer to a lager/pilsner brew schedule but is all this a) Worth while, b) a better schedule for a Baltic porter out there..?

I have only done single temperature fermentation lagers before but the recent acquisition of a temp controller and fridge has created some possibilities.
