your plan could work man just make sure the mothers are fems use preflowers or something i dunno.. but as long as you know your mother is female use it. take the cuttings from the females allways before you go to flower... taking continuous clones in the manner your speaking will eventually lose potency best way to avoid this is take all cuttings before the flower stage... this is the whole reason people use the one mother for as long as they can... but basically if you take the clones during flower they will lose strenghth a lot faster...
lol another thing you may notice is each time you take a cutting it will iether gain fingers on its leaves or lose fingers on its leaves its all to do with generations im fairly sure... just thought id throw that i there its got no real relevance just something to look for...
