Have the same 'Page' under multiple Member Sites possible?

Hi,
 

I am trying to figure out if it is possible to have One Page appear under several different Member Sites. 

So, our site contains 3 different 'tiers' of membership, Silver, Gold and Platina. One gives access to more content than the other. However the, 'highest tier' should ofc give access to all the content while the lower 'tiers' gives access to less and less content. In reality this content is different Pages, and I am trying now to figure out how I can have one single page appear under different 'tiers' of membership. 

Or am I looking in this the wrong way, what would be best practice to be able to give a member of different tiers access to the same Page?

The Pages are behind paywalls.

So instead of having this:

Silver tier - Page url slug called "join-us-form"
Gold tier - Page url slug called "join-us-form-1"
Platina tier - Page url slug called "join-us-form-2"

I just want this, not to need different pages:

Silver tier - Page url slug called "join-us-form"
Gold tier - Page url slug called "join-us-form"
Platina tier - Page url slug called "join-us-form"

But this is not possible today, or I do not know how to do this.

The site becomes so much more complex when everything has to be a new copy of an already existing Page.

Appreciate any and all ideas, and of course, if this is unclear please ask and I will try to explain better. This is our first Squarespace site build.

Best,
Alucard

@TheRealAlucard It seems that I'm trying to figure out how to do something similar to what you are doing. Have you made any progress?

If Sqsp can offer us five different website hosting plans, we should be able to offer five different Member Plans. Why isn't this explained better in the Member Sites help/knowledge content?
