Vader was never a master, but i would only Sidious above him due to what the flanneled one said. Maul was in his prime,(thanks advent for the quote, i just couldnt remember where to look). Once youre topped out, thats it, thats why only one person could be the "one". If anyone could be powerful enough to fulfil the prophecy, then they would have. Now i know that might not be the best example being that Ani never reached his potential, but i think you see where I'm coming from.
Now i think maul could maybe improve slightly on his saber skills he already had, but in no way could ever rival Dooku.
The only problem in advancing much past 3rd degree is finding a suitable Master of higher rank. Palpatine was probably the greatest master of Juyo, so he does have that factor helping his improvement. And Midichloriens don't automatically determine your Ability do they? I'm sure with work they are capable of becoming stronger, it's just harder.
I doubt it would only be "slightly", I'd say he could go up with the greats in saber skill, Force Powers, he could at least learn Grip/Crush like every other Sith.
