Here's a couple of links.
The Original SOR, almost exactly the same:

It has a good discussion of how a Canadian MH is intended to be used.
The MHRS, some changes, but nothing major:

Look at para 4.1.2.5.7.1 of the SOR for the mission system "boxes."
I don't know what Haletown means by putting out current system (paraphrasing) on the AW101. If you mean the Sea King, its no where near the requirement. The Sea King currently has:
- a non-pulse Doppler radar
- a slightly modded AQS-13B sonar
- FLIR-2000 (IR only)
- AIS (not in the MH SOR)
- an emerging Full Motion Video and plot link, but the plot is not Link 11, 16, or 22
The CH-124 is remarkably un-integrated with Canadian Ships. The Canadian Concept is independent ops, full Surface and Sub-Surface spectrum, 4 crew.
If, on the other hand, you mean the mission system from the Cyclone, that would be a considerable effort, and is a big part of the reason we are were we are with the Cyclone.
However, the MH project includes better integration with the ship through MPAS pre and post flight... implementing that would be harder for an OTS buy. The airborne integration is easier at it uses STANAG compliant datalink.
Look at page 21 of this
http://www.nhindustries.com/site/docs_wsw/PDF/NH90_brochure.pdf, its near the SOR. The Merlin is similar except no FLIR, but they can put a MX-15 on a weapon station pod. Either *could* be made to fit the Canadian model.
The 60R does not fit the Canadian model, it is less capable of independent ops.
