I current own: Canon 70-300mm L; Canon 70-200mm; Canon 400mm; Canon 24-105mm; Canon 85mm (the less expensive version); Canon 100mm Macro (the more expensive version and lastly Tamron 24-70mm 2.8.
In that case, I do suggest you have a look at the 6D as well for additional options, as all of your glass will work well with a FF camera.
I don't know pricing in USD for the 6D body, but it may well be a little over the top end of your current budget, especially for a new body. I don't know what the availability of used 6D bodies is - it is a fairly new camera, so probably not too many yet.
I mentioned the 6D because of the own path I ended following: I first got a 350D, followed by 2 400D's, followed by a 40D. Next I got a 5D (MK I) in addition. I stopped using the 40D completely, and got a 5D II not too long thereafter, and never looked back.
Later I did also get a used 1D Mk III, purely for sports photography, which I rarely use to be very honest, as most of my photography does not require a fast camera, or the additional crop factor. It is nice to have it if so required, however.
In short, I think the 60D and the 6D would complement each other nicely, and give you a bunch of additional options you don't have right now. The 24-105 would become a proper standard zoom f.e., opening up new horizons, and the low light capabilities of the 6D are truly awesome. I reckon your lens setup would sing with the 6D, although you would have to get used to it if you have never shot FF before (analog or digital for that matter). And the 60D would always give you that additional crop factor, if and when you need it.
I did shoot film for many years before going to digital, however, that is possibly the only caveat I must offer. I was used to "FF" IOW, which made it a bit of a homecoming for me. Larger and brighter VF, lenses behaving exactly as expected, etc.
HTH, kind regards, Wim
