can i cut this recipe into half? what would be the adjustments if i'm going to make it with 3 egg whites? hope somebody could help me on this... a 5-egg whites won't fit my stand mixer bowl...

ingredients.
1 ¼ cups sugar
2/3 cup water
5 large egg whites
a pinch of cream of tarter
1 pound of butter
1 teaspoon pure vanilla extract

here's the link where i got this recipe from, actually it is a tutorial on how to make IMBC http://www.cakescanada.com/HowTo/IMBC2.pdf

Really, it won't fit? How small is your mixer? For the adjustments, just multiply each amount by 3/5 or 0.6.
