Answer to OP: It might be possible in the future. The tracker itself can already handle multiple chips, all that's needed is a way to enable them (i.e. some check boxes instead of a list). The only thing left is to adapt the NSF code to handle multiple chips and that's probably gonna take some time.
It was mentioned that it isn't possible on the famicom, but that's not quite true. For example the TNS-HFC2 cart makes it possible. One possible reason against it could be that this kind of sound never existed in any games, however it is supported by the NSF format (for some strange reason) and there already are a number of tunes using it so I don't see why not, there will always be the option to not use it.
It's not top priority though, if you want to do it now then you have to use MCK or it2nsf.
