Would rather invest in US Indices for nominal fees that are less than .1%. 1% is a very high fee that reduces the hassle of opening a Zerodha NRO account. 1% is 4 times the fee of Wealthfront, the company you are trying to replicate.
This is also a more efficient way of investing, which leads to higher returns because of low tracking errors. The fee more than covers for itself with the return delta you get here, refer the comment on investing in India ETF vs investing here.
