Alternative to Hommlet Moathouse? Or ways to spice it up?

My players have explored Hole in the Oak and Incandescent Grottoes, most are level 2. They are about to assault the T1 Village of Hommlet Moathouse, and I’m a little worried that it may seem boring after those two excellent modules. Lareth and his cult occupying an old fort has been alluded to by rumors.

Are there any alternative things I could drop in to replace the layout of the moathouse? Or is it interesting enough to run as is?

They only know there’s an abandoned fort, so actually what dungeon is there is really up in the air.

Thanks!
