What's so complicated about it?

The first variable you send through with ＦＰ一時登録汎用 is their battle position (21-26, or technically 11-16 if you wanted to script in an player side character), then it just generates the character the same wa as any generic is generated at recruiting time/start og game, which is to use キャラ生成. You can then perform manipulations on that 'battlefield position' number by using gs[0][assigned number].attribute since 0 is the battlefield.

Not sure if that's what you were going to look into, but I don't think there's much more to it than that.
