Dutch kickboxing isn't really the safest bet for MMA striking imo. Dutch guys like combos, exchanges, staying in the pocket and keeping a high shield guard up. All very dangerous. 4oz gloves will go through or around the high shield. They are also much more damaging so where you could eat some shots with boxing gloves, those same shots could rock you badly or cut you with MMA gloves. Also, high guard means you can't defend takedowns well, and the predictable trend of finishing combos with a kick means wrestlers can have their way if they time it.
Aldo has integrated dutch kickboxing relatively well, so you can look at him for an example of how to pull it off. Still, I'd never fight dutch-style in an MMA fight. Too many risks for me.
Conor McGregor has a perfect striking game for MMA. His defense consists of simply not being there. Where Aldo might choose to shell up and risk getting tagged, Conor gets out of the way completely. No risk involved. He keeps his distance to minimize the chance of the opponent getting lucky, and instead of sticking to combos, only lets one or two powerful shots go in sequence, then exits. 4oz gloves amplify the single shots' power. Much less risk and much more reward that way. Only problem is, you have to be the taller guy to pull it off. It's not an efficient way to fight if you've a shorter reach (eg, Conor vs Diaz). If that is the case, a good example might be RDA. Pre-USADA, he was starching tall outside fighters like Pettis. Had a great low kick and powerful left hand. Decent Muay Thai and dangerous pressure boxing. Again, not really dutch style, but I think his way is better adapted to MMA.
