FA43 is good but not as good as to replace both. The difference is minimum, your FA50 @f2 is probably as good as FA43 @1.9, may be better. I yet to find any convincing comparison for me to replace my FA50 with FA43.
FA35 is perfect indoor and as you said, it's very good for portraits, a small little lens with amazing IQ.
I will suggest to keep both FA35/50 instead of replacing it with one FA43. Another non-technical reason, you will have two lenses, a backup if something goes wrong with one.
