Would Kassadin jungle work?

Would a jungle Kassadin work with devourer? He does some great on-hit damage with W's passive, plus the attack reset would work well with devourer. I'm thinking something like this: http://gameinfo.na.leagueoflegends.com/en/game-info/summoners/masteries/#1q4n6mp8p.BNq6NZX0.0

With all the mana (2050 from items), plus the dive and damage from on-hit procs, it would be a really scary build. The passive mana restore on your w would be huge on champs, allowing you to basically teleport for free even at max stacks. Muramana would be providing over 200 damage on-hit. Basically, it would lay out dps like there's no tomorrow.

Thoughts?
