Customizing priority lookups

[LoriC]

We have been using OOTB priority lookups but have been asked if we can add some other options. The ask is for the default impact and urgency when incidents are created to be 'None' with the priority being set at a 5. 

Additionally, they want to revise Impact = 3- Low and Urgency 3-Low to set the Priority to 4 - Low instead of Priority 5. 

Are there any pitfalls to making these types of changes? Will I have issues with future upgrades where this could potentially break something?

Thanks

@LoriC There is no harm in changing the priority lookups according to the instance needs. Also, don't fret about the upgrades as they are not tightly coupled with any values stored in the priority lookup table. Upgrades mostly skip records/breaks customisations if the changes are done in the OOTB scripts/Widgets/Pages level.
