Leaf mold usually takes about 2yrs, so I started the first year composting by itself, then I added it to a worm bin for the 2nd year. It's a timely process and I wouldn't do it in a bin that you designed to be fast paced. I got worm castings in about 8-10weeks w/o leaf mold, but I did add a handful of some finished looking leaf compost to the worm bin because it was full of worms and eggs. I'm not an expert or anything and I sometimes feel like I'm not good enough to be answering all these tough questions... I'm not really sure how to answer your question, but I feel that mixing it in the worm bin would be the best way. I was having issues with leaf compost before and it seemed to suck all of the iron out of my indoor potting soil, but that is also why the hippies compost companion plants like comfrey, borage, and nettle(etc). I found Lambsquarter growing naturally in my yard, so I stopped mowing the grass in that area so I could harvest it. My yard looks like trash, but I don't care what the neighbors think really. I'm about to pull all of these 6-8ft weeds and compost them. When the leaves fall in Nov, I'll be adding these together...
