depens on what they have to change, The article didn't go into specifics as to what exactly needs to be changed.
If they want to switch from HID to incandesant its going to cost and require more labor to remove the ballasts and rewire the lights, not to mention the fact that HID lights are more effecient and longer lasting than any incadesant.
Now if they wanted to change the HID to a different type IE, HPS to MH you are still going to have to replace the ballast and the bulbs.
If they just want the bulbs to be replaced with powedered bulbs from clear bulbs its not going to be the cheapest since most MH bulbs in the 400 watt range cost around 30~50 dollars and of course you have about 100 in a parking lot its by no means cheap.
Your idea of replacing them when they burn out is good but generaly HID bulbs last for many years. (I forgot the actual number but its rather high)
