No, the API is not generic enough at this point. I hope this can change in the 
future.
This would work:
struct TData2 {
  struct TData {
    float a, b, c, d, e;
  } a2;
} dataArray[N];

float_v x(dataArray, &TData2::a2, &TData2::TData::b, indexes);

Also this is supported:
struct TData {
  float a[5];
} dataArray[N];
float_v x(dataArray, &TData::a, outerIndexes, innerIndexes);

Cheers,
Matthias
