CPU Architecture Independent P/Invoke: Can the DllName or path be “dynamic”?

Question

Is there a way to have the particular DLL referenced by a P/Invoke (DllImport) signature depend on the CPU architecture?

I developed a special library for the target: InteropDotNet. It introduces new RuntimeDllImport attribute with dynamical library path resolving (on the fly). In the default way, you can write

[RuntimeDllImport("NativeLib", 
   CallingConvention = CallingConvention.Cdecl, EntryPoint = "sum")]
int Sum(int a, int b);

And the library will be resolved depends on environment. For example, paths for Win/Linux, x86/x64:

x86/NativeLib.dll
x86/libNativeLib.so
x64/NativeLib.dll
x64/libNativeLib.so
