2 trips to India in a year in Y will take you around 2+ years to score a oneway US/India ticket unless you’re buying very expensive Y tickets. FRA oneway will probably be possible in ~1.5 years.

So you should look at a credit card strategy to supplement your miles.

ORD/EWR are UA hubs and FRA is LHs hub. So it probably makes a little more sense to stick to *A and credit your miles to UA’s MP.

All the major US carriers have 0 YQ on their own and most of their partner flights (BA miles tickets on AA are a noteable exception). They only have a $5-6 security fee.
