Sheesh. Anything is possible, I guess. But, those are pretty big knots and very prominent to boot. That takes a lot of wood out of the bending equation.
Second, those knots toward the ends are really troublesome because you have to work around them, which is complicated, OR include them, which will make for some heavy limbtips, and still be complicated.
You said the narrowest part is 1.35" wide, but you have more width than that through most of the stave, right?
IF I was going to try that, I might actually shorten it by cutting off the worst knots at one end. That one end with three big knots, I can't see any way around. Then, maybe work out the best narrow stave I could by snaking between the knots as much as possible, and including them where I had to. You'll have to run your width lines right up onto the calluses of the knots following grain, but try not to include the actual branch part of the knot. Then you'll have to thin and tiller by following the crown as it wanders side to side around those "roller-coaster" leans and curves.
But, you might pull off something like a 60" character BITH bow. Alternatively, you could pull the best section out of that stave and lash or splice on stiff tips of some sort. OR cut the thing in half, flip it around to find the best bow in the wood, and bolt it to a riser or something like that.
