As I read the Tanach, several reference to David’s Tabernacle being located about 8 miles NW of Jerusalem on the highest point near Gibeon or modern Ej-Jib. Do you see restoring the sacrifices in such a tabernacle if it were built?

By Jewish law after the first temple was built the only place for sacrifices is on Temple mount. That, as you know, is a bit of a political problem beside others...
