As Chojin said, you wont run into serious problems. Just bear in mind that the more you enlarge a subnet, the wider it's broadcast domain will get. This means that when ever a host sends say an ARP request, every one will hear it.
If you have to do more and more enlargements in future, I would start thinking about subneting it into separate VLANs and do routing between them. A second reason to do this, would be to isolate your servers from the rest of your department and be able to apply IP level policies (if that is needed).
But again, nothing wrong with /23 scope
