LE cleared and bigger rivers

[RaktoastTheSandwichTopper]

so i've downloaded SluckyD's gokstad ship mod ( http://skyrim.nexusmods.com/downloads/file.php?id=5432) but i can't go as far inland as i'd like so i'd like to ask someone if you could widen the rivers of skyrim, clear the many rocks, and sand bars, and maybe connect the ones farther inland.

 

if you want you can add more

 

no i might be asking to much of the modder community
