Without some testing, I'm really not sure if you can set a fast enough clock, or mount a significant enough defense, to have a chance at success here. But it will probably be interesting to try!
Here's your problem: While FRoA gives you an effect PS of 9, it does so only for one province at a time. Two 7F units will not take two provinces, but absent intervention, you'll still lose one. You have decent enough static honor gain, but I fear you'll lose provinces (or burn your hand) relatively early to this attrition. You might be able to counteract that, somewhat, with PS enhancers. If you're just going to run one Celestial in this deck, I think the one to choose is Ebisu's Honesty. You might also look at some of the +PS holdings: Merchant Atoll, Indomitable Home, even Fortifications.
You have no counters to honor meta. You probably don't actually have room for them, so that's just something you'll have to deal with. Someone resolving a strong anti-Honor event, like In Time of War or especially On, is probably game; I'm fairly sure you also lose automatically if a Brilliant Cascade Inn hits the table.
