If I replaced the ballast and bulb in this setup with a 250 watt ballast and bulb, basically just using the hqi fixture, would there be any problems?

The de halides use different sockets for the bulbs from 150 to 250's. So besides the ballast, bulb and socket you would need. I have read that its not that hard to do and is doable.

Thanks. I was trying to find the dimensions of the bulbs to figure out if they were different. So I'm guessing that the 250s are larger?

Yes, 250 watt HQI bulbs are longer than 150 watt HQI bulbs. They also use a different socket type and different ballast.
