  The present article is an endeavor to look into some fruitful frameworks
based on "Bi-maximal" neutrino mixing, from a model independent stand. The
possibilities involving the correction or attenuation of the original BM mixing
matrix, followed by GUT-inspired charged lepton correction are invoked. The
"symmetry-basis" thus constructed, accentuates some interesting facets such as:
a modified QLC relation,
$\theta_{12}+\theta_{c}\approx\frac{\pi}{4}-\theta_{13}\cos(n\pi-\delta_{CP})$,
a possible link up between neutrino and charged lepton sectors,
$\theta_{13}^{\nu}=\theta_{12}^{l}\sim\mathcal{O}(\theta_{C})$ or that between
neutrinos and quarks, $\theta_{13}^{\nu}=\theta_{C}$. The study vindicates the
relevance of the Bi-maximal mixing as a first approximation.
