it seems like you're over stressing on a 1% difference in image quality between your camera and the k7- remember the 99% difference comes from, subject, angles, direction and most importantly- lighting, get this right and any camera will give gallery quality images with a decent lens (which you have)
it seems like you value your camera as an object rather than a tool- sure it's nice to feel comfortable with your camera, it makes you want to hold it and want to use it- I always thought like that and I obsessed with the idea of getting a k7 and a battery grip because i'd 'enjoy photography more'- in the end I just stuck with my current camera (6 year old, 6 mp, iso 200 and iso 400 only) and learnt to love photography for the love of the photos, not the camera- now I see the camera as nothing, I hate using it, I don't like the way it feels in my hand so it's always in my bag until I want to shoot something- I just do it to come home with a card full of photos
