You will lose quality, but 99% of the people won't tell the difference when they listen to it. I'm running into the same issue right now since I am archiving my DAT masters recorded at 16bit 48hz.

I suggest saving a straight 48khz "clone" as a flac file and creating 44khz individual flac files for CD burning. That way in case you need one or the other you have both formats available. Memory is cheap anyway.
