If it's within the realm of believability for a single RWBY weapon, then sure, having two weapon modes such as that built into and arm, leg, or wherever is feasible. However, it would have to replace the standard Hunter weapon (the kind that's carried around rather than built in), otherwise you have one of those awful OCs who's trying to be a swordmaster, an engineer, a mauler, a gunslinger, and a utility all at once.

People often argue "but if they can turn their body parts into weapons, why wouldn't they? It's only practical!"

First of all, not everyone who gets a prosthetic limb is going to be able to get a weapon built in, at least not one that matches their fighting style. Something a lot of people seem to forget is that people get prosthetics because they lose their limbs in an accident of some kind; in the case of Hunters, that would likely mean in a fight against Grimm. Let's say Qrow lost an arm and got a prosthetic. What, is he gonna turn his new arm into a scythe, become Reaper from Marvel? No. Yang is just fortunate that her fighting style would be supported by a prosthetic arm, because someone like Weiss or Blake would have been fucked royal. Second of all, practicality in a character is fine, but not when it makes every other character around them look like impractical idiots by comparison.
