Hex-Rays Decompiler is an addition\extension for IDA Pro and I doubt it can work as a separate standalone product.

Please see "Prerequisites" part of Hex-Rays Decompiler Manual:

"The decompiler requires the latest version of IDA..."

https://www.hex-rays.com/products/decompiler/manual/prereq.shtml

But this question, IMO, should be addressed to the Hex-Rays Sales Department.
