A few people have been asking this question despite the sweep possibility on various characters being defined in the match-up thread. Here is the complete list on whom it is and isn't possible on.
Not possible against:
How is this performed? After a light kick tatsu, p-link c.hk~mk after Akuma bounces back to the ground after connecting the tatsu. There is a slight difference in leniency between various characters - Fuerte for example can be tricky to connect this with whereas the window against Balrog is actually quite large. This is likely due to a combination of hitbox sizes and the speed at which characters fall to the ground after the tatsu.
Leniency can also changed if the opponent is pushed quite far back if the lead-in combo to connect the tatsu is lengthy. Practising this will help develop a familiarity as to when it is possible to reliably connect.
* A special case exists for Abel. Focus crumple level 2 > c.mp, c.mp, c.mp xx lk tatsu > c.hk.
Guacamole is awesome.
