/Tse-cy.ss01/Shcha-cy.ss01 - this solution for descenders (so called tails) is great and correct from Cyrillic point of view.
Tse-cy, Shcha-cy, tse-cy, shcha-cy, tse-cy.loclBGR, shcha-cy.loclBGR currently have an unfamiliar for Cyrillic reader gesture in descenders and it would be best to adapt the solution from /Tse-cy.ss01/Shcha-cy.ss01.
Since in handwritten tse-cy.loclBGR, shcha-cy.loclBGR are identical as default shapes I would erase Bulgarian glyphs.
Another form of descenders can be found here. However in my view the solution from /Tse-cy.ss01/Shcha-cy.ss01 would be still a better choice stylistically.
