(assuming you're on a Linux) You can arbitrarily mix 32-bit and 64-bit 
packages with nix. Practically each 64-bit has a working 32-bit version. 
By default you're getting a 64-bit one, unless the package is 
32-bit-only (wine, skype, etc.). If you want to force 32-bit, you can 
use the pkgsi686Linux attribute which should contain a 32-bit version of 
every top-level attribute.
