can I have the cake and eat it too?

No need to be so self-deprecating. If you want a car that doesn't drone as much, that's perfectly fine. Try to get what you want, and maybe you'll get it (and maybe not!). I really hate it when someone has a problem and the response they get is "you should have bought a [Volvo/Prius]", or "learn to live with it".

Sounds like you chose the right course. As mentioned, "drone" is where the exhaust frequency matches the resonant frequency of a panel in the cabin. The fix is to reduce exhaust sound, change the frequency of the exhaust, or change the frequency of the panel which is resonating.

I would start with the hatch floor, and work your way forward until it's resolved. Focus on the middle areas which are directly above the exhaust. Sound deadening isn't that heavy (~.5 lbs per sq ft.), so as long as you aren't a weight freak I don't consider that a huge concern. GL.
