well, no. and yes. :) if you just separate the elements you need to animate as instance collections, well the sky is the limit :). you could press buttons, move mute switch, even you could make some nice ensambling animations.

Well it depends on the reception of this product, but i will be releasing some of my own models sadly with destructive workflow..

Well that depends on your skills, but it will be extremely faster to work with this already prebuilt and make variations, than modelling from scratch.

Yes!, i took a lot of time to model this with this purpose so it becomes easy to reuse or to create variations in minutes. most of the parts are just modified planes to have total control over final detail too.
