The solution would seem to be to train Indian monks and nuns. The recent news was that Barkha Madan, a Bollywood actress, was ordained by Choden Rinpoche and covered in the press as the Bollywood nun. Crass some might argue, but exactly the kind of thing that puts Buddhism on the radar.
Ven. Kabir Saxena is another monk, student of both Lama Zopa Rinpoche and Situ Rinpoche, who is of anglo-indian origin. He ran all of fpmt's activities in Root Institue Bodh Gaya for many years and teaches in Hindi.
The interesting thing is that the one flourishing centre that caters mostly to indians that i know of is Cho Khor Sum Ling in Bangalore, 3 hours from Sera. The monks who teach there are all from sera, and all westerners, rather than tibetan. I have no idea why this is.
This of course is more on the gelug side if things but HH Karmapa for example also has many indians attending his teachings, and hhdl does 1 teaching session per year aimed at Indians and translated into hindi. He always mentions the Nalanda philosophical tradition is an Indian tradition, that the Tibetans inherited.
I would love to see more happen
About the monks, it is unfortunate, and with the nuns' upcoming geshe lharampa exams they will face more competition, probably a goid thing. But at big monasteries like sera, ganden, drepung, namdroling, sherab ling and kyentse shedra, there us still a very good level of study, though i wirry what will happen in 25 years.
More resources spent on reaching out to the indian community is an excellent idea.
A foolish man proclaims his qualifications,
A wise man keeps them secret within.
A straw floats on the surface of water,
But a precious gem placed upon it sinks to the depths
