You should never be messing with the id's that are automatically generated. This is a sure way to mess things up beyond repair.
As i see it you only have the following options:
- Just display the (new) userid. Who cares if there are numbers missing.
- Substract a fix number from the userid and display this as some kind of membernumber.
- Create a User Profile Field to hold an admin set number and display this.
