but :
-sql express database size is limited
-you need to review all the source code ( thouthands of lines)
-you need to know exactly how glpi works to modify.
-you need hundreds of work hours
-you won't be able to upgrade unless you fork again new version from mysql to sql server
so from my point of view it doesn't make sense to use SQL Express .
