My honest opinion is they probably wouldn't get very far, especialy if your planning to go through the Battle Frotier or fight trainers who have pokemon that they've EV trained. I mean why do you think Ash loses the Pokemon League all the time?
Plus the move sets for your Pokemon don't really go well with what they do best. Take your Charmeleon for example: most of the moves you're teaching him are Physical the moves he does better with are special moves the problem is since you're limiting yourself to not evolving them fully they also can't learn the best moves for them. The moves I recomemend for Charmeleon are Flamethrower, Dragon Rage, Ancient Power, and Toxic since those are the most powerful special moves it can learn, Toxic will be a big annoyance to your opponent, and if you're lucky Ancient Power can raise all your stats.
Now lets compare that to a full grown Charizard that can learn even more moves. The moves set I would make for him would be Flamethrower, Dragon Pulse, Solar Beam, and Sunny Day. Flamethrower gets STAB, Dragon Pulse can take care of Dragons threataning to kill an Ice type with a Fire type move and Sunny Day and Solar Beam combined with Charizard's high Speed can destroy all his weaknesses except electric if you use Sunny on your first turn.
Marshstomp is better with Physical moves but if you did evolve it it's a hell of a lot of work to do. Riolu, since you're not planning to evolve it is okay since his Physical is better than his special but if you did evolve him it's special gets much better but his Physical is still high so you can make him either way. Pikachu can go either way evolution or no evolution.
Now the biggest problem is Sableye, out of all the pokemon that can't evolve it's probably one of the worst. Granted he has no weakness and he's a little better with Physical attacks his stats suck so bad that he can't put anything to good use. Spirit Tomb is a much better pokemon since his stats are better but mostly even so there is a lot you can do with customization. Plus your team really really needs the defense he can give.
Now for the sixth you can cover your pokemon well but I think you might need some Omph with attack or defense with that since they are severly weak but honestly I can't think of anything since you seriously love to to restrict your self a lot so I don't think I can help you at all, good luck dude you need all the help you can get.
