I would think it could be done might need to replace the bulb holders as well
Yep.
The other thing you need to keep in mind is that commercial fixtures have cooling designed for a given wattage, as opposed to custom built fixtures where the cooling is usually overbuilt to some extent. So if you simply upgrade the lamps, holders, and ballasts, you'll need to give some concern to keeping the ******** of the fixture cool.
