If the idler sprockets are mounted just below the motor and kinda close to each other you should be able to get close to 180 degrees of wrap on the drive motor sprocket. Basically the chain going over the top sprocket needs to look more like an upside down 'U' instead of an upside down 'V'. the other thing about the idler sprockets is they will make a good tensioning device. That's just my $.02 overall a good weight saving design that just needs some massaging.

To illustrate this idea for you i used paint. This is what i would do if you were going to use a drive system like this.
