Assembly binding redirect towards a merged assembly

For deployment reasons I would like to merge several of our assemblies into a
single assembly. I am able to do this via the ilmerge.exe utility.
Is there a way I can make my application work with this merged assembly
(instead of the 5 original assemblies) without recompiling the other
assemblies ?
Apparently a binding redirect only allows me to specify another version of
the same assembly, not another assembly.

Thanks.
