Strong Scotch Ale - to lager or not to lager

I have had this brew in secondary at 58 degrees for over a month. I recently read an article that some brewers lager their strong scotch ales. I do have that capability. Should I lager this hog for a month or two and then bottle it or just leave well enough alone at 58 degrees? I figured if I have the chance to make my beer even better during the colder months, it would be a shame not too.

If you would have used to edinburg yeast, I wouldn't lager it. But since you used notty, I am curious how it would turn out. I vote do it and let us know. I know that's not alot of help but I don't know alot of people with this tastey predicament
