I don't like holding film for more than a few days. I'm too anxious to see what I shot. No matter what the manufacture says I still like to run my film within a few days. I'm that way about everything though and just can't stand to see thing not completed.
I'm a big believer in testing no matter whether it's ISO or development times. Everyone has a different view of what's ideal so a little fading might be ok.
One thing I thought of, the fading usually occurs in the shadows first. Contact Ilford and see if they have data as to how much fading occurs at the end of the first month then the second during storage at ambient temperature. Use that data to adjust exposure during shooting. For example if 1/2 stop fading accurs in two months, over expose your first film by 1/2 stop. Decrease the amount for film stored 1 month. There also may be some contrast loss and Ilford should be able to tell you. You could adjust development for that if you keep your film in baggies with dates as to when it's shot so you can extend development.
Adjusting exposure for shadows and extending development plus careful storage and notes you can make it work. The degradation should be predictable under average conditions.
