Will my grain bill produce enough fermentables?

[bleedbluesgtr71]

I plan on brewing a roggenbier soon and i want to know what the best ratio would be for my grains. I want to use mainly rye malt and some wheat. I still am relatively new to the science of brewing. Now will i need any other grain in the grain bill to help convert the rye and wheat malt, or will mashing those two plus some vienna or munich malt provide me with my fermentables?

Here's the grain bill from Brewing Classic Styles

6.25 lbs Rye
3.0 lbs Pilsner
3.5 lbs Munich
1.0 lb Caramunich
2.0 oz Carafa II
