Yes.
advancement in roller skates has changed dramatically. when roller skates were invented, they were something like this: a wooden plate resting on two sticks attached with wheels. as scince and technology changed, roller skates also strted to develope. around 1980's the new model of roller skates came out. this time it was much stable and quicker than the previous ones. those skates used ball bearings fitted in the wheels. the top was made of metal. these days they are more advanced. they still use ball bearings, metal top but added with a fluid, which allows to gain a quick and fast speed.
There are a number of accessories that one can buy to to accompany roller hockey skates. There are special wheels and bearings as well as skate tools to use on the skates. There are also skate bags for carrying the skates and, of course, protective gear to wear while skating.

Yes, any skate can take either bearing but you need to have the right type of wheel and spacer per bearing. ie, if you have mini bearings you need mini hub wheels and spacers that fit the mini bearings. If you have standard bearings you need standard hub wheels and spacers that fit the standard bearings.
roller bearings are only needed if engine has roller bearings, u would replace bearings with same bearings that are in engine and cam specs
Roller blades are much faster and better. The roller skates are not as flexible as roller blades are. It's much safer to wear roller blades than roller skates and roller skates are likely to trip you up than roller blades. Also roller blades have more control than roller skates.
