I'm afraid I don't know anything about Vuescan, so I can't really help you 
there. But it seems like you may have forgotten to remove the "GT-X770" line 
from the fs-blacklist. A "make install" may have overwritten your changes if you 
made them earlier.

No, iscan doesn't allow for setting independent X and Y resolutions directly.

According to iscan's NEWS file, the V700 does not require a proprietary plugin 
so doesn't have the same limitation that required you to edit the source. If you 
do end up using the epkowa backend with the V700 you will still need to edit the 
fs-blacklist (remove reference to GT-X900) to be able to scan larger areas at 
higher resolutions. Again, I'll cite the obligatory notice of the 
unsupported/untested nature of doing this.

Happy scanning,
