Disc Brakes or Drum Brakes

Thanks for some of the thoughts. This will not be a full-on restoration. Want to make this a nice around town driver. Can I got to a 15" wheel now with the drum brakes (thinking something along the line fo 15x7 all the way around) and still be able to make the swap to discs without having to buy new wheels again later? Wheels and tires are a must right now. It has been sitting for awhile outside and the tires on the car have all but dry rotted. I believe the car still has the factory rims (13's I think) but I hate to put money in some small tires now when that is not the long term plan.
