"Lifting" (or pulling) on the suction side would be a problem - the literature I've seen seen from Jabsco (even on their low end pumps) says 350 feet of discharge hose or 20' of head....
As long as your discharge is not too small (or too long) the 4' or 5' of llift needed to get into a tank in the P'up should not be any problem.
Note that performance drops off dramatically the more restriction in the hose (head, length, diameter).
IMO, your intended use would be ideal for the Jabsco (or other) macerator systems.
Don't go too small on the discharge side since any restriction will cause the solids to bridge over. I have used 25 feet of 1 1/2" discharge hose on the 345 with good success
