Maybe you can hack i.points.auto to

"seed" it with a priori knowledge or you start with very rough resolution
and then increase it in a cycle to get more precise chips. This would
require source code modification of course to take out the interactive
part (which is obsolete for GRASS 7 anyway and needs to be rewritten).
