Yes there is interest but there are a couple of big problems.
The relativly small NG has limited space for the brakes themself. To provide a reasonable amount of braking performance without overheating requires a large thermal mass. This would seriously affect the size and weight of the NG to get reasonable performance. Look at the amount of brake pack available on the MG of a typical aircraft and imagine how much of that practically would be able to be packaged in the NG. Not much.
Structurally the size and weight of the NG also needs to increase to accomodate the additional braking forces - not a huge issue in itself.
There are performance advantages, but these are severely limited by these factors.
I think I remember reading once that a 727 option was with NG braking, but was rarely used and even then only in a 'suplemental' capacity when full MG braking was used.
