Da sich an der Struktur der Tabelle jos_content im Vergleich der Versionen 1.5.23 und 1.6.0 etwas verändert hat, würde ich mal sagen, dass ein einfaches Wiederherstellen dieser 1.5er Tabelle in eine 1.6er Datenbank mehr kaputt machen würde, als dass es hilft.
Hier die Struktur der 1.6er Tabelle
CREATE TABLE `jos_content` (
`id` int(10) unsigned NOT NULL AUTO_INCREMENT,
`asset_id` int(10) unsigned NOT NULL DEFAULT '0' COMMENT 'FK to the #__assets table.',

`introtext` mediumtext NOT NULL,
`fulltext` mediumtext NOT NULL,
`state` tinyint(3) NOT NULL DEFAULT '0',

Was man natürlich machen kann, ist eine 1.5er Version Deiner Seite leer aufzusetzen, dann die gesicherte DB zurückspeichern, die Seite - und damit die DB - auf 1.6 updaten und dann die jetzt im Stand 1.6 vorliegende Tabelle(n) wieder in die original 1.6er Version der Seite wiederherstellen.
