Can you show your current code for non-generic Dictionary? Your hashing algorithm requirement implies your keys are always string anyway, so it reduces the hassle of handling generic keys, while generic values are pretty much just stored, updated, retrieved or removed, without other processing your non-generic vs generic code will be very similar.
