RE: Flange facing
Think about it, would you not be changing the rating of the flange by reducing its mass?

According to ASME B16.5-2009:
6.3.2 Conversion.
A raised face may be removed from a raised face flange to convert it to a flat face flange, provided that the required dimension, tf, shown in Fig. 7 (Fig. II-7 of Mandatory Appendix II) is maintained.
