You could override the values in a VRT produced by gdal_translate -of VRT
But it is dubious that changing the original values reported by the driver is
going to produce something correct.

There have been recent discussions about why GDAL warping is not appropriate
for datasets that have bow-tie : http://osgeo-org.1560.x6.nabble.com/gdal-dev-
There are a few hints in http://stackoverflow.com/questions/27968890/reproject-
At that time, I see you were looking for a fast(er) gdal_grid. Recently I've
added in trunk (post 2.0) a linear interpolation method which runs several
magnitude of order faster than the other methods.
