I believe it was done all the time, particularly in DHR. The easiest way to check is to look at some of the popular paint programs. If you actually visualize the screen as 140 color pixels by 192, you get very blocky graphics with bad jaggies. You can have 4x the horizontal resolution on a diagonal line just by casting off the shackles of "140 pixels". The same is true of HGR displays, particularly if they are to be viewed in monochrome. I did it myself in some plotting programs. The same mindset that considers there to be a fixed 140 pixels in DHR might also conclude that there are a fixed 140 pixels in HGR as well, neglecting that a white (double) pixel can be plotted in any of 279 horizontal positions. Apple/Video 7 made design choices that pretty well froze them into 140 discrete color pixels across the screen, and that accounts for a lot of the discrepancy between the appearance of an RGB display and a composite display. -michael Parallel computing for 8-bit Apple II's!
