Cela devrait convenir (tenez-moi au courant!) :

SELECT CONCAT(prefixe, '-', LPAD(IF(numero=9999, 0, numero+1), 4, '0'), '-', IF(numero=9999, prochain_suffixe, suffixe)) AS nouvelle_plaque
FROM
(
SELECT plaque, MID(plaque, 1, 2) AS prefixe, (MID(plaque, 4, 4) + 0) AS numero, MID(plaque, 9, 2) AS suffixe, IF(MID(plaque, 10, 1)='Z', CONCAT(CHAR(ASCII(MID(plaque, 9, 1)) + 1), 'A'), CONCAT(MID(plaque, 9, 1), CHAR(ASCII(MID(plaque, 10, 1)) + 1))) AS prochain_suffixe
FROM plaques
ORDER BY suffixe DESC, numero DESC
LIMIT 1
) t
