Yeah, the danger there is lugging carry ons (and mobility-impaired family) across two stops and tight connections. But certainly an option to consider!
I should add that India tickets are purely on my own dollar, so that gives me significantly more price freedom; for example, this year we ponied up extra to avoid SQ’s deep discount fare classes (which don’t accrue to MileagePlus at all).
