Just seems like a waste to go pure int bow and not be a plain nuker...even as pure int spear you'd have higher magic attack, stun moves, new skills and more hp to boot, versus the bow's new moves only. Your crits, one of the advantages of the bow build, would not be effective at all since your str would be so low.
New skills could have made a little difference, but not any lifesaving changes.

Not a favored build though.
That being said, it's up to you! That's the beauty of the game. It's your choice to build it, test it and see what happens...worst case, you can always re-skill as one of the more standard int builds. If it works for you, you'll probably have one of the least used builds in the game.
