No in general Bengali behaves like Devanagri in this respect, Only where KhandaTa is concerned is Malayalam logic true.

It is not clear.

Yes a consonant+Virama+ZWJ shows a half form but what makes you think that a half Ta should look like a KhandaTa?
Why should the Bengali script not be allowed to have a Half Ta?
In some fonts the Bengali half Ta is drawn as a smaller raised Ta whilst khandaTa is given as a separate glyph.
Remember that Khanda Ta is considered a separate character by Bengalis.
