No. Pending us getting some kind of private key (and even then I don't know if it is whitelisted) the only way to run modified xbox games is to have a RGH/JTAG box and also make sure you put the hacked version of the original xbox emulator in the relevant partition. Even then most would probably still say just get an original xbox and mod that, though I am not sure if prices are still quite as rock bottom as they once were.
There are ways to run stock copied disc original xbox games on flashed DVD drives, though things got a bit odd at various points with different updates so I am not sure what goes. Equally 95% of original xbox Scene rips will not be original format, there was a spate of redumps (

Don't think there is much scope for rebuilding isos to the proper format either, especially not if you are more familiar with the more recent stuff on the Wii that rebuilds things from WBFS back to even fully padded stuff, and if they are ripped ones (various groups would tweak files to fit on single layer DVDs/get smaller downloads/be able to do the multi game per disc thing with more still) then good luck again.
