if you do a Hohmann-style rendezvous, you mean that you get there at apogee? Then your speed will be much smaller than a LEO station/satellite. In order to rendezvous you need to match speed as well, which basically means you need to be in LEO as well in this case, so it won't be suborbital anymore. You could drop something which has its own engines to get to LEO of course, but I think that won't be a very efficient way of getting stuff to LEO.

Absolutely!
Going straight up with a VTVL first stage, then ejecting an upper stage which blasts sideways until it's in orbit, could just just about be done. It might even be 'efficient' insofar as the first stage would return to it's launch site with no down-range infrastructure, but in energy terms it would be far from efficient (so much so that even for a large first stage the orbital payload might be of trivial size).
