helpers for setting priors?

e.g. for K, offer a function that uses Raymond et al. 2012 equations to generate a first-cut suggestion for a prior based on your model slope, etc.?

No files, tests, or entry points are identified in the issue. Start by reviewing how the project currently defines model slopes and priors, then compare that interface with the Raymond et al. 2012 equations; done would require an agreed helper scope, inputs, outputs, and validation approach.
