I've done it a few times over the years, I wanted to skate a grosso so i took a 6 hole indy baseplate and used the top hole to mount it and redrilled it through the other 4 holes, moving the wheelbase about 3/8 back. It's kind of stressful, but not too hard to do.
Seems like you can find the dimensions you think work best if you look hard enough, so prob not really warranted.
