When a question includes the phrase, "is it possible" , the answer is 
usually a qualified "yes".

If your question is whether your cosmology is to be preferred over 
other suggestions, the answer is a qualified "maybe".

Unlike most other branches of science, cosmology is not easily set 
up in the lab. The true test over time is not even so much whether an 
idea is "true" as whether it is accepted in light of other things that are 
accepted. 

If your idea predicts something that has not yet been observed, that 
would be a big boost. If you can explain an observation that is 
accepted but deemed "impossible" by other cosmologies, that would 
be a big boost. 

I'm just not sure that you have scored on either of those two accounts 
so that leaves you with just another set of postulates. Would yours be 
more likely to be used? ... that depends on whether people find yours 
to be a more simple, easier to understand theory. If not, new theories 
are usually ignored because they do not benefit anyone by adopting 
something new. 

Today, the trend is to increase the number of dimensions and not to 
think of anything as having only two.
