Granted, I am fully aware that I could be waaaay off the mark here, but to me, after perusing these forums a bit, would seem like it would work.
If you are specced like this...

If you hit premed, then ambush, could you end up with 5 CP from 1 ambush?
2 from premed
1 from ambush itself
(If Ambush Crits)
1 from initiative
1 from Seal fate
So, assuming this is right, you could ambush then 5 CP evis shortly thereafter, right?
Part 2 of the question...is it worth it to do that?
PS- i know the build may be a little off, (esp assassination tree) but I was really just wondering about the seal fate / premed combo
