Maybe, but it's not easy. Neither were the older ones.
I don't know if you have seen what is necessary but this is the general idea:
1. Open up the eMac
2. Essentially dissect it to get to the internal parts Apple doesn't want you touching
3. Move some TINY jumpers
4. Do some soldering
5. Put back together your eMac
It's not for the average power user. It's really not worth the trouble IMO, but if you want to do it badly and don't mind voiding your warrant and/or damaging the eMac, then maybe you'd be willing to pay a technician to do it for you.
