There are several compound risers that make good recurves when limbs are added to them. I have fixed up about 6 different ones. As a general rule, the limb pad angle needs to be 15 degrees or less. I have bought the economy Samick and greatree limbs, my 4H kids shoot them well! This is called Warfing or Quarfing. Warf is a term coined by Bob Gordon, who reworked several BEar risers to use ILF limbs with improvised fittings and hand tools. Quarfs are risers that Use Quinn limbs, through altering the riser. I have mades som fine shooting bows off these, and the new Martin Jaguar is a compound Riser with Recurve limbs also!
