Arjun, it is very clear to everybot that you "cannot see how".
But several people already invited you to read Unicode documentation and
find out how this all this stuff is supposed to work! Look at the past
messages in this discussion: they are stuffed with links to on-line document
that answer your questions.
The fact that you keep on saying the same things, with no refinations since
your first post, clearly shows that you have not done this effort.
Sorry, but I think that it is useless discussing something with someone who
does not want to understand what others are saying.

No. This is not possible. This would change* the meaning of existing
Unicode characters and, consequently, would break all existing applications.
This is one of the most definite "NO"'s in Unicode policies.

It is all the other way round: Unicode is just for storing text in files and
databases. The process of displaying text on screen is left to a
specialized part of the operating systems.

Why ever!? The ZWJ ("zero-width joiner") is an Unicode character as any
other (its hexadecimal code is 0x200D). If a database can store Unicode
characters, it can also store ZWJ.
By the way: you perhaps misunderstood me on a point. ZWJ is normally *not*
needed to form half forms. An half form is normally displayed automatically
when a consonant is followed by a halant and another consonant.
ZWJ is only needed when you want to show an half form *not* followed by a
consonant. This is only needed in special cases, e.g. when your text talks
about grammar, spelling, Unicode, typography, and so on.
