It's not a question of can but a question of whether actual Quinn fans want one or not. Considering she isn't a LI, I seriously doubt that she'll get two completely different character arcs so it's going to be one or the other.
Except it wouldn't be different character arcs, it would just be one as it would be part of her overall character development.
We start off seeing her as this hard-edged, bitchy character whose single-mindedly determined to make money through illicit means, but then we also get glimpses of a scared and vulnerable side too. So, if something were to happen that causes her ventures to collapse and she ends up in potentially serious trouble, then that other side might come out a little more and help her to grow as a character as she, and likely the MC, set about trying to put things right.
To me, it feels like the underlying story of this game, the connective tissue, is Quinn and her shady businesses, that what happens there is going to impact the MC, and by extension his various relationships and the other characters around him.
