Absolutely. There are many options as nearly every major brand produces a hollow axel crankset. If yours is creaking than I suggest changing the bottom bracket as well, unless you're sure it's the crankset (chainring bolts can creak). Have a look at Shimano's Alfine crankset for a start. The main technical aspect to note is the axel diameter. Shimano and many others make 24mm axels. Sram and some others do 30mm.

Hope that helps.
