I would imagine your strategy would work if the L.E.D.s were in series with the I.F. valve anode load (I.F.T.). The current would ,I guess, be about right if you use low current L.E.D.s The output stage anode current would swamp any perceived variation due to A.G.C. action if they were in the H.T. line I suspect.
