Questions re: 3 or 4way blue switches + zigbee group to Hue bulbs

You can do what you are looking for.

Group EP1’s of all switches and lights together.

Bind EP2’s of all individual switches to that group.

then you have 3+ “remotes” for 1 “light group” that includes the dimmers.

Remember to wire smart, meaning all switches will have hot/neutral at all times, no traveller, and only one will be the load switch which will need to be in SBM.
