Nice thread, Ken-P, I like how you approach this whole project and wish you much success with it.
Personally I'd like to add following suggestions:
Mystic Ark
Gokinjo Bouken Tai
Lennus 2
Shining (Force) series (personally the Sonic/Camelot developed games up until Shining Force 3, I'm sure many would appreciate Shining Force 2 in particular)
Baten Kaitos series
For something really obscure I'd love to hear an orchestration of Wolfteam's Zan series.
(Though of Wolfteam's output the games best known the West would be Sol Feace, El Viento and Earnest Evans.)
