I have had a life time of moving boats around that weight across beaches on my own TSM ..so my first thought is why would you consider transom wheels in the first place ..they are designed for lightweight SIBs ?
This small hardshell that I owned for many years weighed 150Kg and the last thing I would fit to it is transom wheels. I have never seen a hardshell boat of that weight fitted with them although Im sure perhaps someone somewhere has ? I used the trailer to launch and recover it. I used an electric winch to pull it up and down the beach..or a long rope tied to the car if space was there to tow it off the shore. I could shove it on my own down a smooth beach on a trailer.. but needed mech aids to get it back up the beach. If I unhitched it on a slipway..the weight would have pulled me down the ramp after it. I had to have a rope wrapped round the tow hitch to stop it running away
My Quicksilver is around 120-130 Kg bare boat ..and I tried home made transom wheels on it.. on their own it was not feasible for me to move on my own.. but by using inflatable roller boats to assist the bow I could just manage to move it across shores..but I seldom did it as it is very hard work. It was as easy using the trailer with wheels on the drawbar ..so I dumped that idea.
Of course..you have not said how many will be assisting you ..or what kind of surface you are crossing..so Im sure it is possible if you have the mechanical means to assist.. the people ..and also most importantly..the masochistic will to do it.
From my experience for small boats (not SIBs) inflatable rollers are OK ..but a trailer / trolley is best.
