In our self-similar, analytical, magneto-hydrodynamic (MHD) accretion-ejection solution, the density at base of outflow is explicitly dependent on disk accretion rate - a unique property this class solutions. We had earlier found that ejection index $p >\sim 0.1 (\dot{M}_{acc} \propto r^p ) $ key MHD parameter decides if flow can cause absorption lines in high resolution X-ray spectra black hole binaries. Here we choose 3 dense warm solutions with = 0.1, 0.3, 0.45$ and carefully develop methodology to generate which are convolved Athena XRISM response functions predict what they will observe seeing through such outflows. paper two other external parameters were varied extent disk, $\rm{r_o|_{max}} 10^5, \, 10^6 \,\, \rm{r_G}$, angle line sight, $i \sim 10 25^{\circ}$. Resultant (H He-like Fe, Ca, Ar) change strength their profiles manifest varying degrees asymmetry. checked a) ii) asymmetries detected, suit synthetic spectra. Our analysis shows should detect for standard 100 ksec observation mCrab source equivalent width as low few eV be detected 6-8 keV counts larger than $10^4 10^5$ even least favourable simulated cases.
