The load current will be approximately \$I_{\small{LOAD}}\approx\frac{V_{\small{Z}}-700\:\text{mV}}{R_{\small{E}}}\$. You will need to accept the fact that there will only be a compliance voltage for the load of \$\le V_{\small{SRC}}-V_{\small{Z}}\$. And \$I_{\small{LOAD}} \le 10\cdot I_{\small{Z}}\$.
