1. X are well
2. Y is mother of Z
3. Additive merge: Z&Y
4. Intersective merge: (Z&Y)+X

I haven't worked on reciprocals since the 1990s, but casting my mind back to then, I recall there were a range of reciprocal predicates (for things like "each member of X ... every other member of X", "each member of X ... every member of X", "each member of X broda some other member of X and each member of X se broda some other member of X", and so forth). Roughly speaking they're dyadic predicate with one argument a plural and the other a ka-phrase containing two ce'u (-- Lojbanizing the explication).
But you're right that additive merger offers new possibilities for reciprocals of a sort that neutralize the reflexive--reciprocal distinction.
1. X is mother of Y
2. Additive merge: X&Y
3. Z loves Z's self [= inflectional reflexive]
4. Intersective merge: Z+(X&Y)
1. X is mother of Y
2. Additive merge: X&Y
3. Z loves W
4. Intersective merge: Z+(X&Y)
5. V du U
6. Intersective merge: V+(Z+(X&Y))
7. Intersective merge: U+W
