To get that you'll need a scanner capable of 7200 DPI of resolution. That's the easy part. 7200 pixels per inch is 284 per millimeter or 142 lp/mm. To get that resolution, you'll need to stop down no further than f/11. So, on 8x10, you'll need to find a lens capable of over 140 lp/mm across the frame and also not stop down past f/11, which will vastly limit your ability to get enough DOF for many images, and yes even with movements.
Sorry to burst your bubble but that ain't happening. The resolution of film is one thing, actually achieving that kind of resolution in practice is another. Realistically, most newer digital cameras equal or surpass 4x5 if shot properly with a decent lens. I can show you examples of this from a camera released 8 years ago...I haven't even tried the newer 40-50mp DSLRs, which will surpass my earlier test.
Anyway, none of this really matters. I shoot film for the ability to print it in my darkroom and make handmade SG prints. Though, I now have the ability to print from digital files too to SG paper, so...
