As Mr Selfish says, your FW CIR will alleviate 20 hours of IFR dual instruction. You will just need to do 20 hours dual on a helicopter - this doesn't have to be an IFR helicopter!!! The test must be done on an IFR certified aircraft.
I know it is tough (financially) but if you can, bypass the single engine IFR route. It is a waste of money if you intend to get an IFR position. The ME IFR route will give you much more of a chance for employment and it covers SE.
Give me a yell and I will do the flight test for you!!
