Come on surely as experenced instructors you don't need to get checked out per say just use common sense.
All the trike SEP's I have flown have the same picture on approach and if you nail that, the speed sorts itself out if you do the normal apparoach grad.
As for the rest of the handling have a look at the book, have a taxi and and a couple of fast stops.
Go fly it at medium weight,
Go high and run through the stalling exercises and have a steep turn or two. See what its like near the stall.
At a suitable speed throw it around a bit and see what the control responces are like. Do a PFL.
Then go an do a couple of normal circuits at book speeds different configs then do a fast approach and see how much it floats.
Then if everything feels normal and comfy, then go teach in it.
5 hours is just an arbitory number with no requirment for actually learning the envelope.
