Merging has nothing to do with tlogs. Tlogs are simply the last N (configurable) raw documents to be used for certain index recovery operations.
Dynamic fields are no different from static fields. In either case the first time a document is encountered with a field that matches, the same mechanisms take over so I'm not sure what "cost" you're talking about here.... There are costs associated with having 1,000 fields, but whether they're dynamic or static fields doesn't matter.
