Dont get confused between what the FMS can do, and the limitations which the helicopter is certified for in section 1 of the RFM. (PAGE 1-7) The Vmini is 50 KIAS. So no matter what modes you use, you are not certified to use them in IMC below 50. ( Although it is badly worded, and described as minimum speed for flight in IFR - clearly you can fly IFR in VMC. The key point is, you need to be >50 kts if you are in cloud. That is why, for example you would do a clear area profile in low visibility, because your VToss also happens to be Vmini - you get to a safe IMC speed before you go into cloud.
