You can go with the internal, but at least on the 12F675 you have 4mhz internal, so your conversions are a little slower. See the TAD vs device operating frequencies part of your schematic. 1.6 us if fastest. Looks like 4mhz would be 2.0 us. So as long as you are not using 16 bit, you probably won't notice the difference in speed, and you will save one more part in your part count.
