If there were to be a meter with colour awareness into the IR region, it would be dandy to be able to select the film type (loaded as a curve into the meter) or at least be able to define a custom curve. But it means a meter manufacturer needs to make a programmable meter, possibly augmented with built-in or add-on filter sets. Imagine, you don't set the ISO, you select the film itself. Everything taken care of.
An Leica M8 and a steep cut IR and steep cut Red filter would do, they are getting cheaper, the steep cut IR was free with new ones (M8) for a while. If the meter fails trash can.
A custom meter might be more expensive.
