Body Filler for Inner Fenders

If you're that worried, would it be that hard to section in the pieces in question? I'd think once the filler was more than 5-6 inches away from the exhaust, there'd be no issue. Is this a street car, resto, race car....?

Its going to be a race car, but I would like to get the area better looking while it is all apart. I did the best I could with the welder and grinder, but there are still some pin holes and a bit of waviness I would like to smooth out. Also, I added a picture to the original post of the area in question.
