As to I want to increase the size of cake diameter but want to use some krispie treat as well could some one please help me.

I'm not quite picturing what you mean - will you elaborate? I may just be dense tonight, but I was confused when I read it, lol!

After the first sentence I am lost. Are you talking about one of those cakes where it has a road that goes around the cake?

Are you looking for something like this:

But with the roads supported by RKT instead of being carved out of your cake?

do you mean the road made out of RKT? like a "ledge"? I am picturing something, but im not sure if its what you are looking for
