Decomposing numbers into arbitrary bases *already* exists as showIntAtBase. Vikas's proposal is about generalizing this existing function to output more than just strings and characters. Whether the existing naming scheme makes sense is a separate issue. (The whole Numeric module is weird, from the non-hierarchical name through function like showFFloatAlt.)

Please let me know thoughts/concerns if any to this proposal.

That is, you want to decompose a number into digits of an arbitrary base? I would not associate that with "show". I have implemented this in some flavors:
