Claiming to be IFR in VFR conditions as an excuse to get a 'better' service or 'more attention' is reprehensible in my humble opinion.
I think you've fallen into the old trap of mixing up terminology - there's no such thing as 'VFR conditions' and you presumably mean VMC.
Any pilot can choose to fly IFR under VMC in Class G airspace if so wished and he/she can elect to ask for a Radar service irrespective of in flight conditions. He/she might not get one in Class G, or any service at all, but that's the luck of the draw.
However, if you put further restraints on yourself, that's your perogative.
