Not sure if you're still in need, but I came up with these very generalized rules for hexcrawl and similar types of travel and exploration. Feel free to crib any bits you think might be of use:

The rules there are significantly inspired by Nate Treme's "In the Light of a Ghost Star":

And a bit of "Ryuutama: Natural Fantasy Roleplay":
