In round trip transliteration between Indic scripts,
a one-to-one letter correspondence between Tamil
letters and other Indic scripts exist, and works
quite well.
This fact is recorded in the Tamil chapter of
the Unicode standard also. The unicode std.
mentions using 2,3,4 as subscripts on the
Tamil letters (k, c, T, t, p in transliteration).
There are hundreds of books existing using
2,3,4 as subscripts or superscripts upon
க், ச், ட், த், ப் (= k, c, T, t, p respectively in transliteration)
to transliterate voiced and aspirated letters
(called varga letters of k, c, T, t, p) on Indic scripts
into Tamil.
A proposal to change the text in the Standard
mentioning 2,3,4 as subscripts and superscripts
can easily be done. In it, will provide usage samples
from Kannada, Telugu, Sanskrit, Hindi etc.,
Because Tamil script is non-conjunct these
2,3,4 super(sub)scripts come in handy.
Tamil script is for writing Tamil language books,
Of course, in Tamil Grantha script to write
Sanskrit texts, the "varga" letters are independently
defined, and they also conjugate heavily.
The main difference between the two Southern scripts
is the language it uses, the sort order and
the nature of conjuncts in each.

Quite untrue.
Devanagari and other Indic scripts'
aspirated letters are never written in Tamil script
books with Aytham (in Unicode, Tamil Visarga sign).
The super(/sub) scripts 2 and 4 are used
for unvoiced aspirate and voiced aspirate letter
for each of the 5 varga letter in Tamil script
transliteration.
