Ouuff difficult.
The nitsch in particular is attractive but will certainly come back, and of course amp pairing is also important.
Is this the Verite open or closed you're talking about?
The Atrium open, if you get used to it, can be really laid back and enjoyable, it's the perfect opposite of the Verite, it's more neutral, faster and more open.
The Atrium is warmer, more enveloping and also slower compared to the Verite because of the biocellulose driver, more relaxed and also transparent at the same time, more air in the room of course.
It rather depends on your listening preferences, but if the BO was already sufficient for what you are looking for then yes, but it will also be slightly below the class of the Verite and not quite have the range of it, you should be aware of that.
Also because the Bokeh is still a mobile headphone whether open or closed.
About the amplifier, if it is so limited and has a long waiting time, it might be more of a priority than headphones as you can order from Zmf any day as soon as you are ready for it.
