Swinging Choke vs Series Resistor for SCR-Diode Bridge Rectifier LC Filter Design

We designed a single phase AC(50Hz) to DC converter with a full wave half controlled SCR-Diode bridge rectifier and LC filter on DC side. The LC filter is mainly to limit output ripple. In addition to attenuate ripple which we calculate at full load; we intend to maintain good voltage regulation from no load to full load.So we wanted to explore swinging choke option where inductance changes with load current (low current-high inductance; high current-low inductance) so that our system acts as a choke fed filter at no/light load condition & capacitor fed filter at full load thereby maintaining output nearly constant from no load to full load.But we got to know from the manufacturer that a swinging choke only has a range of inductance change for a given change of current. Our current range from no load to full load is too much of a change and the real inductance will never coincide. Instead, we can add a resistor in series with the choke but will make up the loss.Please suggest any other method to have good ripple attenuation along with good voltage regulation with a LC filter? 

I have seen people also doing as below.

Hi Deepak-There's a good paper about designing with swinging chokes here: Step-gap "E" core swinging chokesHow much ripple is acceptable at full load?It sounds like you've already spent a lot of time and effort on the 50Hz design, but if this had been a switching supply, the power transformer and filter circuits would have been MUCH smaller!-Rick 

Hi Mr. RickThanks for your reply..
I have already seen the paper you referred; but I don't have the expertise to make it ourselves. 
2% ripple is acceptable at full load.
The only reason for using SCR power converter is that our customer needs only  this.
