I was going to suggest a sequencer too, but was trying to stick with modules Scott probably already has.  

Scott,  you could use the clock out of the A-190-1 thru the 160 to get the division you want, then perhaps use half a 162 and half the 170 to shape your signal.  But keep in mind that these signals (as well as your repeating ADSR idea) would all be 0V-5V, rather than the typical -2.5 to +2.5V or -5 to +5V of a normal LFO.  

Also, using the Reset In on a Doepfer LFO and tuning the rate would only work (easily) in studio settings, as changing tracks and therefore tempo would require retuning of the rate.
