Hi Bill; welcome to the board. Pretty much every Epic I've seen has a set neck rather than a neck through. So if you're looking for a fretless Epic, it's pretty much going to be a set neck.
I feel the same as you; I think, generally, trading your fretted for a fretless is preferable to pulling the frets on an Alembic. You might also consider purchasing a fretless and selling the fretted if you can't find someone willing to trade. If you watch this board regularly, someone at some point will probably be selling a fretless.
