nitrous users please read!

I have a '90 GT with a mildly modified motor. The mods are listed in my sig. I am running a 150hp shot of nitrous. My question is about gapping the spark plugs. I have a Crane HI-6 ignition with a Crane PS-91 coil, which obviously puts out a more powerful spark then the stock Ford ignition. So I'd like to take advantage of that better spark. I only use my nitrous maybe once a month, if that...so I'd like to have a bigger gap than the .035 that running nitrous calls for. In a "perfect world" I'd like to run the gap at .035 on the juice and like .060 when just on motor. Is there a happy medium anywhere between those 2 numbers where I'd still be safe with the nitrous? Say like .045? Or do I have to change plugs everytime I want to use the nitrous? What are you street/strip nitrous users running your gaps at?
