I do not what different entities at design.
@Tricky, you are right - use configurtion but do it as late as possible. How you can control structure through "generic" you will should used "generate" after all? it is better to write procedure/fucntion. but it is another level of programming.
Okay. How many architecture you could provide for full-adder for 3 32-bit words or for 6 64-bit words? How you can compare it in one step in design cycle/what about simulation. WE stop here and say for ownself "there a lot of ready-made code. why not just using it". I answer for myself "let's modify that code to meet my project requirments".

Just instantiate two adders instead of two architectures and assign to two outputs. In practice I never need to do more than one architecture. Universities love it.
