The only solution I can come up with is prefiltering the prerendered backgrouds. Even then only so much blending etc. can be done to an improve the image. The most complex method of image pixel expansion is to use data fitting. This involves generating cubic splines that fit the curve of the pixel intensity changes. Depending on the expansion ration IE 2:1 3:1 4:1 the larger it is the more affective this technique is. It gives the best image but at a VERY high performance penalty.
Wen 320x240 expanded say 3:1 is 960 x 720. The advantage of a one time expansion on a background image is that it can be slown without really being anoying. Most other techniques require you to constantly update the background image with a new image. A single expansion is it. The big drawback with this is MDEC movies. With those there is not much you can really do. It's best to let those play pixely along since a simple linear expansion of the data is not going to slow things down much but adding FSAA will.
There really is no good solution to be honest. Since in all ways you are far exceeding the original systems capabilties. Especially in games like FF7 .. with the scrolling 2 D backgrounds you'll notice that well.. it's not as cool looking as it was at 320x240. Bottom line is there is only so much you can do about it other than making NEW backgrounds.
