Is Glave Prime Blades and Ember Prime BP worth buying with plat?

So with upcoming melee/secondary dual wielding, I really want to get the Glave Prime and the only part that I'm missing is 2 Blades. Along Glave is Ember which I have her Neuroptic,Chassis and systems but still needs the BP.

So should I get them both or what should I skip? Since they just got unvaulted,I think their prices will only go up as time goes on and I don't know when will they come back.
