Thanks.  I installed this, but please review the composition rules,
because in the Syloti Nagri greeting some characters whose Unicode
general-category property is Mn, which means they are combining
characters, don't compose.  That doesn't feel right to me, but I don't
read this script.  Just go through the greeting with C-f and type
"C-u C-x =" at every cursor position: you will see some of the
characters are shown as "combining", but they don't compose with
surrounding characters.

I didn't look at the other scripts you added, but maybe they, too,
have similar problems.
