Panel Changes
No, the panel is not "structural" in that the airplane flight loads are not carried through/by it. I categorize aircraft structure as "primary" and "secondary", and I would say the panel is a secondary structure. It carries the weight of the avionics attached to it.
So as far as the changes you illustrate in your Solidworks model, I would say it would be OK. However, you appear to have the support ribs from the firewall for the slider canopy, and these are structural. So be careful where you put your avionics in the panel so you don't have to compromise (ie. cut and then have to reinforce) the ribs.
Also, the panel is not very wide, and angling the avionics toward the pilot may not be necessary. It's easy in Solidworks to forget the actual size of things. I plotted mine out on an E size drawing full size and then got a blueprint shop to plot it full size. In my case, I fastened it to the actual panel in the fuselage and tried out the ergonomics from the pilot seat. If you're not that far along, you can still do a quick physical mockup to check the switch throws, radio buttons etc.
