If you had any sense, you'd get yourself an IR(R) then build some PIC/IFR time while hour-building, practising instrument flying for real, to save yourself some time/money when it comes to doing the IR and you can do the "competency based" version and hopefully pass with fewer training hours than the old 55/45 hour route.
Find someone with a Frasca sim (one at our school, £25/hour) or practice on a PC flightsim if you must. Not really any value in doing what you've suggested.
