The problem is exactly as stated, sending multiple fields to the _same_ destination in copyField directives requires that the destination field be multiValued, so you can't do what you're describing unless the destination field is multiValued.
There is no requirement that faceting be performed on single-valued fields. But this seems like an XY problem. From the naming of your fields (suggest_facet) I'm not sure you want to deal with faceting at all. Are you trying to implement autosuggest perhaps? It would be useful if you stated the user problem you're trying to solve, because on the surface it looks like you're not going down the best path. That may just mean I don't understand the problem at all. And I'm quite ignorant of what special handling is necessary for autosuggest in Japanese so may be way off base here.
