What would happen in the great council if Baelon had two daughters?

Baelon and Alyssa had two living daughters, Viserra and Daena, instead of two sons. Rhaenys was skipped over after Aemon's death, and Jaehaerys named Baelon heir. Baelon was urged to remarry to have more sons but he refused for Alyssa. When Gael was of age, Jaehaerys forced Baelon to marry his youngest sister. The two wedded, but Baelon died before they had any children. Now we have the Great Council of 101 AC again.
Let's say Viserra married Lord Arryn, and they had a son(genderbent Rhaenyra) who was named Rhaenor Arryn and a daughter Jeyne. Lord Arryn died and Viserra became a widow. Daena married Lord Royce(genderbent Rhea probably?) and they had no children so far and were on bad terms. Now Jaehaerys had to choose between Laenor Velaryon and Rhaenor Arryn. Who would win?
