Enlarge lasts only a minute? I guess maybe with Haste you could get more done in that short a time.
The only thing that Gnomes ever brought to the game was the illusionist multi-class ability. Otherwise the Dwarf is better in every way, except unless you prefer having a big nose. But with no racial class limitations anymore, and no uniqueness to the Illusionist spell list since 2E+ implemented the awful mage specialization sub-classes, there is really no reason for gnomes to exist in any way other than garden ornamentation.
