Before you get too far with this, I tried to find an internal cross and failed - not sure what this means, but it is unlikely any model updates are available.
The OPA2690 is a similar topology internally, but not as high a supply voltage,
Well, modifying the TI model would require product line attention - and, they will likely find many other things to improve on that model.
Anyway, before they take off on that, here is a parametric search for close parts (TI/NSM only, LTC does also have a similar dual). The LM7372 looks promising from a spec fit standpoint, - this is VFA sorted descending Slew Rate, Looks like it might be a slight decomp on the LM6172. So, if you have any gain at all should be fine,
And, TINA V11 has a model for the LM7372, testing it for input noise looks pretty darn good - 1/f and flatband looks right,
Here is the TINA file for this, there is always a question of model validity across other specs, but the noise voltage looks good, This test ckt emphasizes the input voltage noise for the op amp itself.
And, the LM7372 is still in the older parametric cross reference (the LM6172 is not). These are abysmal crosses, but it does show a different database list of parameters for the LM73272 re-iterating that 14nV flatband noise in the sim and the previous parametric list.
