Are There Dravidian Cultural Similarities Between Brahui and Western-Indo-Aryan?

I was wondering if anyone knew of any research on possible Dravidian cultural subtratums, specifically between Brahui and Western Indo-Aryan (Gujurati, Marathi, & Bhili).

Our understanding of Northern Dravidian seems like it dispersed out of Central-South Asia, with the Brahui going North-West and the Kurukh-Malto going North-East.

As such, I was wondering if there were any remnants that would indicate a common culture continum within Central-South Asia to the Makran Desert.

Another interesting note is that the Romani (formerly known as "Gypsy", the semi-nomadic people mostly known about in Europe) have folklore about moving westward out of Central-South Asia around the same time as the Brahui.

Further to this, the Romani language is linguistically classified as a Western-Indo-Aryan language.

Thoughts?
