Sure, a Change Items in List node — like the existing Change Item in List, but inputting multiple Positions and multiple New Items — sounds good. Opened for voting.
Bodysoulspirit or Xavierdev, did you have a specific example in mind where the Change Item Ranges in List node would be useful? Unless you do, we plan to skip this node and just add the Change Items in List node. Since a Change Item Ranges in List node would have several input ports that you'd have to coordinate to make sure the data is entered consistently in all of them (correct number of list items, etc.), we're thinking the complexity of the ports would outweigh the convenience of being able to use ranges.
