Power steering was introduced mid-year during the 1953 model year. In my opinion, adding a complete factory power steering from a 53 or 54 (they are almost identical and would both fit) would do nothing to detract from the value of the car, and might well add value. Not everyone cares about 100% correctness (look at the modified cars crossing the auction block at BJ and garnering big bucks), but most hobbyists appreciate vintage equipment. Again, just my opinion. An additional benefit is that the car would be more enjoyable to drive, which is probably why you are considering adding power steering in the first place.
If you do decide to add power steering, make sure you get ALL the parts required. There are some parts that are unique to power steering that you may not be aware are different, like all the shifting mechanism on top of the column, the fresh air ducting on the driver side, the idler arm, even the left motor mount tower is different.
Here's a complete power steering system for a 54 with Powerglide:
