I feel like the combo of steam gauge six pack and glass nav is the best of both worlds. Some may disagree
If not required, consider putting the money from the 650 into the G500 or nextgen Garmin PFD/MFD (easy for me to say), but seriously, if money is somewhat of a concern, I honestly don't think you will find using both GTNs that useful. As you know, you will find a second Nav/Comm or just a Comm very useful, but I don't think paying for a 650 to have a second comm makes sense if not mandated by the regs.
VORs and ILSs may go away, but probably not soon. If you like redundancy, it's being able to make an approach when GPS RAIM predictions are unfavorable and the GPS satellites are down (2 GPSs aren't going to help here). Whether or not VORs/ILSs go away doesn't really matter to you anyway since you would have a VOR/ILS receiver for your 750.
I hope you end up doing the G500/750/ADS-B/MVP.
