My point was that you should not do so. If you want to report marginal
effects for interaction terms than you'll have to live with the fact
that they vary widely and report it as such. There is no single number
that can meaningfully summarize the marginal effect of interaction
terms, they are just too variable.

Hope this helps,
Maarten
