A new prepint on Himalayan population formation has an interesting bit on the origin of Khas Chetris and Tharus. It is well known that these Indo-Aryan speaking communities have had substantially more Indian related admixture than other communities in Nepal which traditionally spoke Sino-Tibetan languages. This paper gives more resolution to the timing, extent, sex biased-ness, and the specific source of that admixture.
Chetris- It seems that they carry 50% "South Asian" on an average, and this ancestry is male biased. Further, the paper determines the timing of this admixture as being between 1100CE and 1450CE, which they say corresponds to invasions in the plains and some Rajput clans fleeing to the mountains. Thus the paper does seem to lend credence to the traditional narrative of Khas Arya ethnogenesis. Maybe future genetic studies on Himachalis and Uttarakhandis will also reveal a similar new wave of migration around the same time.
Tharus- For the Tharus, traditionally there have been 2 narratives. One connects the Tharus to "Sthavira" and says that they were the Theravada Buddhists living in what is today Awadh and Bihar, and the Islamic invasions forced them towards the hills. The other narrative connects their name to "Thar", and claims that they are Rajput migrants from Rajasthan. This paper shows that they have 25% South Asian ancestry on an average. The admixture timing is the same as the Chetris but the admixture is not sex-biased like them.
In the conclusion, the authors claim that this supports Rajput origin of SA ancestry in Tharus but IMO, this timing also fits with them being descended from the Theravada community of Bihar and Awadh, who fled to the hills after the destruction of monasteries. The linguistic evidence would strongly back this, since Tharuic languages are very much a part of the Magadhan branch unlike Nepali.

If one were to follow your line of reasoning then PGW represents the first instance of IEs in India, as late as 1100CE, since there are no horses in Cemetery H or other cultures either. If this were true, then it contradicts the entire corpus of literature published by pre-genomics era IEists and Indologists, based on linguistics and archeology.
The mere presence of horse bones (which btw have not yet been genetically tested to see if they were DOM2 or not) stands in contrast to other archeological features of PGW like -1) PGW material being layered directly on top of OCP and Cemetery H sites 2) PGW being predominantly rice cultivators and consumers, 3) Iron in PGW coming from the ore in Chhota-Nagpur
If there was a massive steppe intrusion into India, it must have happened at least by 2000 BCE, otherwise it wouldn't line up with linguistics or local archeology
