If you rewind, he had talked about tiruppugazh, which I don't disagree outright, but to get the contemporary musical aesthetics, for kAdi mOdi, it can be taken in triSra naDai, caturaSra jampai tALam - for the 21. kAdi , mOdi itself is in triSra gati from a syllabic perspective!
After that post, there has been a specific demo of the same by SrI tAyumAnavar during May 2018 SrI Pazhani remembrance day.
he demonstrates the canda tALa, immediately noting the difficulty of doing it these days. Converts it to miSra jampa with the last sollu of laghu done as 3 instead of 2 (for the equivalent kAla pramANam). That makes 10*2 = 20 into 21 to accomodate the 21 akshara tirupugazh line.
That is a hybrid solution - giving the flavor of canda tALam within a standard sUlAdi tALA structure.
Then he finally goes into full triSra naDai mode where he picks triSra tripuTA. This is similar to catuSra jampa that I suggested. With catuSra jampa, kAdi mOdi vadAdu nUl - the subject fits into pURvAnga almost with "nUl " , where the dhIrga goes over anudRtam (saSabda kriyA). While kaTriduvORum does an atItam to the second one. These are there in triSra tripuTa as well , the first one in the vAdADu.
