Mike, yes, with that size, it is attainable.
I would build a bend thru the handle or D style, profile.
As for curing, leave the bark on and seal the ends. You could bring inside, basement or garage, for a month or so.
I personally, would pick the best side, few knots, straight looking bark, and remove the belly side with a drawknife. Take down to rough dimensions and seal the belly, and cure for another month or so.
Then you can remove, scrape the bark off, and work from there!
You could have a finished bow by spring!
Sapling, limb bows are some of my favorites!
Al Herrin, wrote of the Cherokee elders, making and hunting with limb bows of osage of short limbs! Have fun with it and let us know the outcome!
