For a re-negotiation to produce significant results, you need (1) a partner, and (2) an "or else" option the other side wants to avoid. IOW DemAr's position seems suicidal and weaker than I expected. However, what if there is a troika-critical majority in parliament? Would they be capable of seeing SYRIZA as the supplier of the "or else" option? if not, then it would appear to me that only a collapse of ND would provide for an outcome presenting any hope for Greece.
