The early 20th century presented us with several monumental works on Halachah. The top 3 stars in the firmament seem to be:
1 Mishnah Brurah [MB]
2 Aruch haShulchan [AhS]
3 Kaf haHayyim [KhH]
It may be too late. The ship may have sailed. Many newer posqim probably have superseded the Big 3
What if someone circa 1950 created a new Kitzur using those 3 as his Beth Din? *
And Is it too late NOW to do a modified version?
How about a newer BD that would combine a later generation?
1 R Moshe Feinstein [RMF]
2 R Ovadiah Yosef [ROY]
Perhaps we could create a Kitzur based upon the latter BD
It would be nice to synthesize the opinions of the dominant posqim. And at times a synthesis, a blend can produce a balanced outcome
See the R Mordechai Eliyahu edition of Kitzur SA for a sampling of what I am advocating.
* NB RY Caro set up a hypothetical BD of Rif, Rambam, and Rosh
Also Kitzur SA - RS Ganzfried - set up a similar BD of SA haRav, Hayyei Adam, and Derech Hayyim (R Yaaqov of Lisa)
How slavishly these authors followed their own rules - is beyond the scope of this post.
